Finally Rebuilding: Need Help
Hi guys
Now at last, after the obvious delay during the start of Euro2004, I'm rebuilding the computer! I just want to do it right this time with connections and BIOS settings etc so I need some help. If it crashes today after this test, it's off to the hardware store for a new psu.
(1) I have the BIOS that came as standard pre-installed in the retail boxed MSI motherboard. I bought this in February or early March, can't recall.... I don't know what version it is ... do I need to upgrade? I've never "flashed" anything before ... how do I do it? Is it worth it?
(2) I'm connecting my two sata HDDs to the VIA controller ... not raid, just two separate drives. When I F6 on the Windows XP installation, I insert the VIA drivers floppy that came with teh motherboard. I install the following drivers:
(a) VIA ATA driver for Windows XP
(b) VIA SATA RAID driver for Windows XP
.... is that correct or do I just want (b) ?
(3) Before anything else, do I need to "clear the CMOS jumper"? What exactly does this mean and how is it done? Is it necessary?
(4) Do I need to enable/disable any BIOS settings just to get up and running?
(5) I want to run the following programs to test the system:
------ Memtest86
------ the newer version of Memtest from wonkanoby's site
------ Prime95
I haven't got a clue how to do this or what to do ... I'm reading about "blend tests" and "torture tests" and "large FFTs" and I need some seeeerious explanation
By the end of this test, I hope to establish that my memory and cpu are not faulty and are not overheating, so I just need to return/change the psu. As it stands, I might have more faulty components and ned to return them too.
Thanks for your help.

p.s. .... some of you asked how I had HDD LED working on the VIA controller. Well, the red light on the case came on whenever the HDD was doing a read or write, but there was no case light ... I probabaly had the connectors the wrong way round. I had:
ON JFP1-----------------------
* Reset Switch = on pins 7 & 5 with the label facing outwards ... i.e. at the Promise controller
* HDD LED = on pins 1 & 3, label facing same way as Reset Switch
* Power Switch = on pins 8 & 6, label facing oposite direction from HDD LED and Reset Switch ... i.e. with the label facing the bottom of the case and the white wire connected to the "+" sign on pin 6, the black wire connected to the "-" sign on pin 8.
* My case has no 2-pin connector for Power LED on JFP1 ... instead it has a 3pin connector for Power LED on JFP2 ... is that why I get no Power LED?
ON JFP2---------------------
* 3pin Power LED = on pins 1,3,5 ... label facing outwards towards Promise controller
* 4pin Speaker = on pins 2,4,6,8 ... label facing oposite of Power LED ... i.e. facing bottom of case.
My PC has crashed again. This, however, is totally different to the previous problem. That does indeed seem to have been caused by a faulty cpu cooler installation and automatic hardware shutdown due to overheating. That problem resulted (every time) in a total hardware collapse, so that all fans would stop, the monitor would go black and essentially all electricity would stop flowing in the computer. You would then need to go to the mains socket and turn it OFF-ON before being able to use the Power button on the case. Once I found that the cpu cooler was loose on the motherboard (and that it could actually lose contact with the cpu when the case was upright), I reinstalled it, using the correct backplate (I had been using the wrong one before). Since then, the same problem has nver occured and the pc has been running fine for about 10 days with no problems whatsoever. Until now...
This problem is different. The fans keep spinning and there is no trouble with electricity. Instead, Windows XP just seems to freeze. It happened when I visited a website. I was using a proper firewall and antivirus program (updated very recently). It just froze for a few seconds ... I tried ctrl-alt-del but that didn't work so I just pressed the Power button on the case to shutdown. This freezing problem occured from time to time on my Windows95 PC and pressing the Power button is the only way to fix it. When you restart, Scandisk starts but you just exit immediately and there are no problems. It occurs on Windows95 when I have a lot of multitasking going on, which is probably due to lack of Ram (32 mb). This new PC, however, has 1024mb of Ram. I've checked the Ram extensively using the Microsoft Memory Diagnostic Tool (boot from floppy) it passed every possible test configuration without any errors. Anyway, back to my story ... when I pressed the Power button, nothing happened but a few seconds later, the PC "unfroze" and the mouse cursor became moveable again. Windows then shutdown properly (on Win95 it just literally zaps off when you press the Power button ... XP obviously controlls the process more carefully).
The PC then started back fine and I went back online and then shut the PC off for the night. This morning, whilst using the internet again, the PC froze the same way. ... Shut the PC down and then turned it back on .... Upon restart, a blue screen saying "UNMOUNTABLE BOOT VOLUME" appeared. I've seen this before, once or twice, with the previous problem. Subsequent attempts at restarting the machine led to the follwing black screen.
Windows XP was unable to start up normally, please select how you would like to start up:
Safe Mode
Safe Mode with Prompt
Last Known Good Configuration
Normal Mode
.... Windows will start up in Normal Mode in (xx seconds [counting down])
I tried all apart from Safe Mode with Prompt (it probably won't work if Safe Mode didn't work and I don't want to get into command line operations right now). When you select a mode for restart, e.g. Normal Mode, it goes along fine for the first few seconds and then when the Windows XP splashscreen appears, it stalls. The blue progress bar under the Windows XP logo keeps moving from end to end repeatedly but it doesn't move on from there. It stays there for about 30 seconds and then the same blue screen appears again.
It seems to be a software problem (probably with Windows) but I did notice one unusual thing with hardware. When it froze last night whilst I was online, the hard drive started making sporadic "beep" noises that I haven't heard before. When starting Windows up now (and failing), the same "beep" noises come again. In addition to these "beep" noises, the hard drive starts spinning (the slight high-pitch whine noise) and then seems to restart ... i.e. the whine dies down for a second and then restarts, like spinning slows down and then the disk spins up again. Hard drive corruption would seem a bit unlikely, as it's been running fine for a week now with no problems and the hard drives are on their own (not in the SmartDrives anymore), running at perfectly normal temperatures.
Any suggestions? I was thinking of running chkdsk.
By The Way:
I managed to transfer all my files from my Windows95 and Windows3.1 PCs, by connecting their HDDs to my new PC and using copy-paste in "My Computer". The Windows3.1 HDD took a while longer and a couple of restarts of XP before it would show up, but it worked. These were installed under a couple of subdirectories called something like:
/myOldWin95PC
/myOldWin3.1PC
I copied the whole drive, so Windows95 and Windows3.1 and DOS were copied too. Was this a bad idea for conflicts etc? I deleted the Windows3.1 and DOS folders and just kept the data. Windows XP is supposed to have protection against such conflicts anyway.
Thanks for all your help everyone.

}I've basically used the structure of other programs and incorporated them into my design. If anyone knows how i can fix the errors please let me know. The errors are found in line 91 and 100 which is where the zoom slider is occuring.
**NOTE** the program isnt fully functional in the sense that there are buttons and tabs etc.. that are missing action listeners and things like that.
Thanks for the help

The code was on the forums as the person who posted it was using it as an example in a program he used... i didnt borrow the entire code im just using the way he did the zoom method and added it into my program. I wasnt aware that it was used in the JPanel class. C'mon, it's your program. If you don't know what you are doing in this program, then you shouldn't be using it.
That is why im asking if someone can show me the right way to implement a zoom slider into my program or maybe give me an example where its used.What the fuck is a zoom slider???

I shot footage using a Canon XA10 and there are issues with the HD quality not looking as crisp as it should. I am trying to make sure the settings in Final Cut are right. Need help confirming what should be in "Field Dominance" --- have seen discussions about making sure it's set to "none" but I'm confused as to what to do.
Also someone suggested I use "drop frames" to change from 30p to 24p within Final Cut. He couldn't explain how to do it so any input appreciated as well as any thoughts on whether this is a good option to try.If you're shooting 30p, field dominance should be set to none. Since you need to use log and transfer to bring this material in to fcp, I would assume it would be set correctly automatically. Are you sure you've set the camera properly?
Drop frames will not change 30 p to 24p. Dropframe timecode simply refers to the number assigned to each frame which drops an occasional number (not any frames) so the timecode duration is the actual duration, since 30p videoi is actually 29.97 frames per second which each frame assigned a timecode number.
This is very basic video stuff and requires some basic knowledge of video. Wikipedia is a pretty good resource for much of this stuff plus there are lots of great resources on the web. Look up interlaced and progressive video, 24p and 30p.
And as far as judging quality, you can only get an accurate view of the quality in fcp when you have a video card attached to a video monitor. The viewer and canvas are only an approximation of what the quality is. Minimally, set the canvas or viewer to 100% to get a better approximation of the quality. -

I need help. How to export split track for Final Cut Pro 7 Thanks
I need help. I have edited a film and now the company I have made the film for want a split track of it. I have no idea how to export a split track off Final Cut Pro 7 and I need simple language to explain it to me as I am a beginner. Thanks
I assume you have multiple tracks of audio? And the audio is distributed discretely over these tracks (sync sound on tracks 1 and 2, sound effects on tracks 3 and 4, music on tracks 5 and 6 for example)?
Then duplicate your sequence by clicking on the icon for your sequence in the FCP browser and control-clicking on it. From the drop-down menu choose Duplicate. Double click on the duplicate sequence you just created to load it to the timeline and canvas.
Now, working on the copy you just made of your finished sequence, click anywhere on the timeline, and type Command + 0 {zero} to bring up your sequence settings. Click on the Audio Outputs Tab.
Once the Audio Output Tab opens, set the Outputs to the desired number of discrete tracks you want to export - in this case I will set it to 8, as I have sync sound on tracks 1 & 2, Voice Over on tracks 3 & 4, Sound Effects on tracks 5 & 6 and Music on tracks 7 & 8.
Once I do that the 8 tracks appear. I set them all to Dual Mono as I want them to be discrete tracks:
Once I am done, I click OK and return to the far left side of the timeline where the audio selectors are, and carefully control - clicking in the empty space above the lock symbol,
From the drop down menu I assign the output of each track - track 1 to to output track 1, track 2 to output track 2, doing so to each track:
You need to set the output for each track. Once all my track assignments are done, I go to the menu File > Export . . . > QuickTime Movie and export my sequence, but now it is exporting with 8 discrete tracks of audio.
To do a quick check that everything is OK, re-import the movie you just exported back into FCP, and open it in the Viewer and you will see that it does indeed have the multi-tracks, as 8 mono track tabs appear at the top of the viewer.
Now give that QuickTime a name that includes "Split Tracks" in the title and copy it to your delivery drive.

Imovie user needs help in final cut!
hi, i am an imovie editor who has made the smart move to final cut pro. but i am confused sometimes on what to do. i am editing a promo video for my school, i have an audio clip that runs the whole promo (voiceover)and i want to cut out a piece of it out. in imovie i would just "split" the audio at the beginning and end, reselect it and delete it. not sure how to do it in final cut. any help would be much appreciated. thanks
aaronTo do that same technique in FCP... use the B tool (for razor).
If you hit it once, it will only cut items linked at a certain spot... if you hit it twice it will cut the whole timeline.
Then... use the del key over by HOME and the media on the timeline will close when you delete the selected material. If you just want to LIFE out the section and leave the hole... use the delete key by the += key.
Yes?
Good luck and welcome!

Need help in creating a java program
Hi everyone.
I'd like to say before i start about my problem, that i've only begun learning java and my teacher hasn't explained anything at all. He only showed us by doing it himself and then showing us the final version. I've searched a little on how to program but i get little success in finding a good tutorial.
I need help creating a program which has been assigned to me due in a few days in which i can't contact my teacher for help.
I need to write a java program which inputs 3 items. The number of kilometres you drove, the number of litres of gas you used and the price you paid for the gas. Then, the program must calculate the number of litres used per 100km driven, which is litres divided by kilometres times 100, how much it costs to drive 100km, which is the result (a) times the price per litre and the number of miles per American gallon of gas ( one American gallon = 3.785 litres, and one mile = 1.609 km.
The program has to output my name, the inputs given, the results computed and a message saying "Program Complete".
To give you what i've done to begin with, from what i understood, is:
import javax.swing.JOptionPane;
public class prog1
public static void main(String args[])
final double americanGallon = 3.785;
final double mile = 1.609;
kilometresDriven,
gasUsed;
priceOfLiterGas;
System.out.println("My Name");
System.out.println("Number of kilometres driven:");
kilometresDriven = JOptionPane.showInputDialog ("Kilometres Driven");
System.out.println("Number of Litres of gas used:");
gasUsed = JOptionPane.showInputDialog ("Litres of gas used");
System.out.println("Price of a liter of gas:");
priceOfLiterGas = JoptionPane.showInputDialog("Price per liter");
Up to now, that's all i've got. i know i'm wrong, but i'm not sure how to do this. Could someone give me an outline of what this program is suppose to look like?
Thanks in advance.Here's an update on my program. I've worked on certain details and would need your comments whether it contains errors. I'd also want to know if it would work or not because i don't know how to check it on my computer.
Here's the update:
import javax.swing.JOptionPane;
public class Prog1
public static void main(String args[])
String name;
double kmDriven;
double litresUsed;
double pricePaidForGas;
double priceOfALiter;
name = JOptionPane.showInputDialog("Name");
input = JOptionPane.showInputDialog("Number of km driven");
kmDriven = Double.parseDouble (input);
input = JOptionPane.showInputDialog("Number of litres of gas used");
litresUsed = Double.parseDouble (input);
input = JOptionPane.showInputDialog("Price paid for gas");
pricePaidForGas = Double.parseDouble (input);
input = JOptionPane.showInputDialog("Price of a litre of gas");
priceOfALiter = Double.parseDouble (input);
a = (litresUsed/kmDriven)*100;
b = ((litresUsed/kmDriven)*100)*priceOfALiter);
c = (kmDriven/1.609)
System.out.println("Name:" + name);
System.out.println("Number of litres used per 100km:" + a);
System.out.println("Cost of driving 100km" + b);
System.out.println("Number of miles per American Gallon of Gas:" + c);
System.out.println("Program Complete");
System.exit(0);
Comments please.
Thanks in advance -
Need help making ball move and bounce off of sides of JPanel
I'm currently working on a program that creates a ball of random color. I'm trying to make the ball move around the JPanel it is contained in and if it hits a wall it should bounce off of it. I have been able to draw the ball and make it fill with a random color. However, I cannot get it to move around and bounce off the walls. Below is the code for the class that creates the ball. Should I possible be using multithreads? As part of the project requirements I will need to utilizes threads and include a runnable. However, I wanted to get it working with one first and than add to it as the final product needs to include new balls being added with each mouse click. Any help would be appreciated.
Thanks

Newbie needs help with Flex app
Hi there. I am very new to Flex and also fairly new to
programming although I do have a little experience.
I am trying to create an app which stores code snippets or
common text I tend to use every day in my documents and emails.
So basically I need help on a design level. I can refer to
the developer's manual for exact instructions for commands, but I
need to know what to code first.
The app will consist of:
-a tree directory structure where I can create groups.
-There will be a basic text editor where I input all my data,
basic text formatting options (font, bullets etc) would be a bonus.
-A search function
-Finally it will ideally allow multiple client apps write to
a central database file over a network
Can anyone suggest how I should approach such a project?
Or are there any tutorials / source files which demonstrate
each bullet point?
thanks.Hey jono,
I'm new too. But I think I might know the right components.
If you google any of these + flex 3 you should get some
decent documentation
tree - advanced dataGrid component
basic text editor - rich text editor component
search function - well, you're gonna need to read up on
arrays, and arraycollection. Once you get that stuff working, you
can write up a function to search for a string in an array.
network functionality - HTTPService, you can dump the
datagrid into a database, and have it load the database when you
open up the application.
Give these things a shot, tutorials / sources will come with
the google searches. -
first of all, who has heard of the game called zuul? It is a very boring text based game I am currently having the pleasure of improving.
Basically, you are in a room, that is connected to a bunch of other rooms and depending on the room you are in, you have different exists and different items in the room.
The goal is to navigate through the collection of Rooms and there is no real win condition, It is more for learning then for actually playing.
You navigate by a series of commands such as: go (direction)( as in "direction of exit", NSEW), quit, a few other odd bits.
ex: go south, quit, go west etc
The game has several classes: Game, Command, CommandWords, Item, Parser, Room.
Obviously Game is the main central head conch, (it is not the super class.)
Game makes use of Item, Room, Parser, and Command.
Item is the class that deals with the number of items in the Room.
Room is the class that deals with the rooms the player will navigate to and from.
Command reads in the commands such as "go-(direction)" or "quit".
Parser makes everybody understand each other by using both Command and CommandWords.
CommandWords is a list of commands such as "go", "quit" etc.
The problem I am having right now is to allow a player to move through the rooms while holding a certain item. The item has to come from the rooms and the player should be able to drop it.
So I have to add two new commands: take and drop. The problem is that I have been asked to do this without creating a new class. Otherwise I would have just created class Player and be done with it. So I am trying to figure out whose responsibility should it be to take care of the take and drop command. I have done some preliminary work in class Game, it is the take(Command command) and drop() methods.
I have also a few questions concerning other aspects of the project, I have listed their locations here:
1. The take() method in class Game, the for-each loop, a complier error with ArrayList
2. class Parser, a general question about the string tokenzier
If you want to see how the game is suppose to run, just comment out the bodies of take() and drop(). Not the declaration. Everything else works.
I shall now provide the code to all classes. I wish there were an option to upload a zip file, then you don't have to read through all the codes and copy&paste all the codes. The complier I am using is BlueJ. And the SDK version is 1.6. With the exception of class Game, everything else can be assumed to be error free.
Thank you for your time,
Davy

Setting Up New FCP5 HD Bay -- Need Help
I'm setting up an HD edit bay for a friend, and I have a number of questions. Any help would be a godsend.
Basically, he's got a G5 with Final Cut Studio installed, a Motu audio interface, a Mackie Mixer, a Decklink Pro HD dual link, M-audio LX4 5.1 speakers, and a DVD/VHS recorder. He has one 250G internal capture drive, and one external 1TB firewire G-Raid. He's running a 23" and 20" Cinema Displays, and a Panasonic 32" HD LCD Flatscreen.
He wants to rent decks per project for capture and output.
My questions is this, how do we output to SD VHS/DVD or other formats for clients? Do we need a Switcher? Is it possible to do format conversion in Final Cut and output via Firewire instead of decklink to SD devices?
Also, is SDI (serial digital interface) cross-platform from SD to HD? Kramer Electonics has an interesting format converter that supports SDI, but will that change HD to SD? Here is a model number and link. FC-7402
http://www.kramerelectronics.com/indexes/item.asp?pic=71
Kramer also has a firewire format converter that looks interesting. FC-20
http://www.kramerelectronics.com/indexes/item.asp?pic=430
One of the Mac Vendors suggested the Blackmagic Multibridge Extreme, which sounds perfect, but costs $2000 - 3000.
I'm looking for a low cost alternative, if possible.
I really need help from someone experienced with this. I'm a freelance editor who cuts offline mostly on Avid for episodic TV, but my friend master HD out of his Mac edit suite. This is new territory for me.
Thanks in advance.You should setup your local DNS to resolve only for the 'film.lab.' domain. Any requests that your local DNS will not be authoritative for should be forwarded to your district's DNS server. You should also set your local DNS to allow recursion only for clients on the 10.x.x.x subnet. The failure of clients configured to use your DNS for name resolution could be due to rules that have bee setup on your district's edge router to block outbound and inbound port 53 requests for all internal clients.
If you set your server and clients to use your district's DNS server as the secondary for your zone, you must make certain that any hostnames within your local zone are defined on your district's DNS to resolve to the private, 10.x.x.x, subnet that you will be running your systems on. If you don't -and your DNS goes down and there is no secondary defined on the clients that contains the zone info for your subnet- your clients won't be able to find any hosts. If you wish to run services that will be accessible from the Internet on your local server, this may require your network admins to make changes to routing to allow those request to be pass from the public network to the private one.
Also, if your district runs a central DHCP server you will need your district network admins to setup their DHCP server to return the correct client settings for your DNS and search domains for the clients within your subnet. If they do run a central DHCP server, do not attempt to set up a local one for your subnet. If you do, the probability that you will receive a very angry phone call from a not so happy fellow at your district is very high.
