MSI845PE Max2: booting from the RAID controller

Hi,
I have an MSI 845PE Max2 motherboard. This board comes with 2 extra IDE connectors from an onboard RAID controller. I managed to put this controller to work as a regular UDMA133 controller with an modified BIOS.
I have a CD-ROM connected to one of those IDE connectors. The CD-ROM is detected, but I didn't manage to boot from that drive.
I tried to alter the boot sequence on the BIOS. I even disabled the 3 pre-configured steps, leaving the option "Try other devices" enabled, but still wasn't able to boot from the CD-ROM.
So, this is my question: it there any way to get a drive (wether it is a CD-ROM or a hard drive) to boot, when it is connected to the RAID/UDMA133 controller?
Best regards,
Norberto Henriques

I Download mod bios and went to flash and the Msi instructions on flashing were insufficent for the job. For one thing when I got to A prompt after bios. There was no c drive detected. Couldn't get to bios in C:test. Hard drive was connected to Ide 3 where i installed it with the 133 drivers during installation. I tried connecting it to Ide 1 to see if it would boot. It did and seemed to work but still couldn't get to c drive from A prompt after bios with C: . Tried booting with Me Boot Disk (the one I installed Me with on other systems). There was no ramdisk loaded. It just acted like I wanted to install Me. I gave up on the flash (but still would like to know how??) Got my maching running with 430watt antec, msi 845pe max2-fir, 40 and 60 gig maxtor 133 drives, pent 4 2.4B ghz. asus Dvdrom and Asus cdrw,512Mb crucial 2700,Radeon 8500LE,Sound Blaster 5.1. Had only a few problems. Still trying to figure out some of the Bios settings. Will post more later if anyone can help. P.S. How do you get all your statistics to show up at the end of your post without typing it out each time?? Any help appreciated. May the force be with you

[VIA] Cannot Boot From SATA PCI Controller With On Board RAID Enabled

Hi.
I have a KT3 ULTRA 2 with onboard RAID controller. I have installed a SUNIX 2 port SATA PCI Controller which works perfectly & appears in the selectable boot devices. This is not a problem except for the fact that I have 4 devices on the On-Board Raid Controller. When the on-board raid controller is enabled, the SATA device dissapears from the boot options & I can no longer boot from the SATA controller.
Any help is greatly appreciated.
Many Thanks

I had already tried that....
I set the boot sequence to use the SATA card & then renabled the on-board raid, but after reboot the sata card is not available as a possible boot device & asks me to insert system disk...even if the boot sequence is set to boot from other devices.
Really annoyying this, looks like I am going to have to get a different motherboard for something so silly. I am already at the latest bios release.

Can I install Snow Leopard and boot from software RAID 1 (mirror)?

I have a Mac Pro (quad core 2.66 GHz) on order for my office workstation. Yeah, I know new ones are probably coming out early next year but due to budget and upcoming projects I need one now. What I'd like to do is replace the pre-installed 640GB drive with two 1 TB drives and mirror them. The 640GB drive will be redeployed to another machine in the office. Can I boot from the Snow Leopard install DVD, go to Disk Utility, setup a RAID 1 with the two drives, install Snow Leopard to the mirror and then boot off the mirror set?
I've searched and found offhand comments to the effect that installing to and booting from a software mirror is OK, but I'd like to know for sure that it's OK. Any experience that you have with such a configuration would be nice to hear.

Yes. But before you do read the following:

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?

Can't boot from IDE RAID 0 on K7D

I'm running the K7D with the latest BIOS, with two MP 2000+ processors. In PCI32 slot 1 is my adaptec 1200A IDE RAID controller, with one WD Caviar 1200JB set as the master drive on each of the card's IDE channels.
With the drives set for RAID 1 (mirroring), I have no problems. I can install Windows 2000 Professional, and I used it for weeks with no significant problems.
With the drives set for RAID 0 (striping), Windows 2000 installs just fine, but the K7D will not boot from the array. If I boot from a floppy or a CDROM, The Win2K boot loader has no problems loading win2k from the RAID 0 set. But the K7D does not find an MBR on the array.
Where could the problem lie? My Award BIOS boot order is CDROM, SCSI, HDD0. The array is marked as bootable in the RAID card setup.

no Paazel...
this is the right forum for him
his board uses the AMD chipset... this is the AMD chipset forum...
i think he has a MSI K7D Master-L 760 MPX
witch is a dual prossesor mobo. with the AMD chipset.

10.3 Server new install won't boot from Mirrored RAID - HELP!!

Hi all,
I had 10.3 Server running fine on a 450 MHz B&W G3 (home server use, nothing too demanding), when I decided to add a 2nd HD and run the server from a RAID mirror (both 80GB drives). I had problems enabling RAID on the boot drive with diskutil in Terminal, so I decided to rebuild the server. I didn't have much besides the system on it, so backing up data and re-installing isn't a big ordeal (or so I thought).
No problems creating the mirror set once I re-formatted the drives. The install seemed to go fine (10.3.4 on install disk), but upon restart, I got the flashing system folder/question mark. When booting from the install disk, Disk Utility recognizes the RAID, and Startup Disk recognizes the mirror as a viable boot drive and allows me to select it and restart. Same problem, no system found.
When I run diskutil info for the mirror, it lists the mirror volume as Not Bootable.
I've checked the disks with both Disk Utility and DiskWarrior - all looks OK. I've reset PRAM and NVRAM, taken out added PCI cards, and disconnected all FW and USB devices (besides kbd and mouse).
Unfortunately, B&W G3 can't boot from an external FW drive, so I'm stuck with booting from a CD/DVD for troubleshooting.
My next step is to re-install on a single drive again and try to enable RAID and mirror, but I'd sure like to avoid that if I could.
I've searched through this board and didn't really see this particular situation. Any of you smart server folks seen this before -- any ideas or suggestions??
TIA,
Brad
B&W G3 Mac OS X (10.3.4) 450 MHz, 10.3 Server, 80GB RAID mirror

if you backup your data from a NON-RAID Drive (Single drive), create a RAID array and then Restore from the backup you created... you will find you cannot boot from the drive.
Apparently the sector or drive header information in a non-RAID drive is different than in a RAID array... so when you restore the backup data from the non-RAID drive to the new RAID Array; you effectively corrupt the RAID array not allowing it to be booted from.
The solution is to create the RAID array and then re-install your system from scratch... copying over the data you want to keep from your initial backup one file at a time (don't do a complete system copy or you will once again, corrupt your new RAID install).
I had the same problem and it took me a great deal of time to figure it out.

Moving from VIA RAID controller to another RAID controller?!?

Hello
I'm going to install a RAID-1 with 2 SATA harddisks from seagate using the onboard VT8237 RAID controller of my KT6 Delta.
I guess there should be no problems and that the temperature on the motherboard will be fine.
However, what will happen if I want to move later on to a new motherboard with another raid controller or install a dedicated RAID controller?!?
Will I loose all my data? Or will the new raid controller duplicate the data based on the source drive?
Thanks
JohnQM

I have read somewhere that the following migration paths apply for raid:
1. raid-1 can always be migrated to a new RAID controller, no matter which brand, because raid-1 is just a mirror and no important information is written in the partition table
2. raid-0 or other raid-levels
2.0 from one brand of RAID controller to the same version of the RAID controller of the same brand: no problem
2.1 from one brand of RAID controller to a new version of the RAID controller of the same brand: usually no problem (upwards compatible)
2.1 from one brand of RAID controller to a RAID controller of another brand: no go
Can someone confirm this please?
Thanks

Will mavericks boot from a raid array?

Will OS X Mavericks boot from a raid array? I know Lion didn't support booting from a RAID.

Well, since no one seems to want to answer this question I've done a little research and answered it myself. Yes, you can boot from a RAID while running OS X Mavericks. The only setback is that you can't create a recovery partition.
While installing Mavericks on a RAID it will prompt you to OK installing without a recovery partition. In laymen's terms it means you have to keep your own backup. If your RAID fails you will lose the data or whatever is stored on it. Simply keep your own backup and you'll be fine. This is the way most people do it anyway. Yes, it may be considered old wave but it's still the best option. It's an absolute. If you have a backup, you never to have cross your fingers, pray and hope the recovery process actually works!
That being said, you can create some really souped up Macs. I actually installed two 480GB SSDs into a 2.8GHz Macbook Pro and the response is phenominal !!! From power on button to sign in screen is less than 10 seconds on a 5 year old Macbook Pro !!! If you hate seeing the little spinning wheel while shutting down this will cure your distress. Shutting down is instantaneous. I love it !!! RAID and SSDs are the best !!! A newer Quad-Core machine has to be even faster which is hard to imagine.
That's my 2 cents ...

Trying to install SL on a new hard-drive for my iMac, when asked which disk to install on it gave me no options, i followed advice from another forum and created a partition, now can't boot from the new drive at all. Help?

I've had **** with my iMac, the hard-drive failed so i replaced it with a new 1TB Samsung drive. Then when i tried to install SL from the install disk, all went to plan until it asked me which drive i wanted to install it on, where it came up with a box where my options should have been, but instead it didn't give me any options to install it on any drive i.e. it asked which drive i wanted to install it on but no drives came up to select.
So i followed the advice from another forum, look at the 'Extended Hard-drive preparation' response
( https://discussions.apple.com/message/10576009#10576009 )
After following these instructions i have now got a new partition, but when i restarted my computer to install SL on the drive, the option to boot from the drive is now not available, now i must boot from the install disk, whereas before i was able to boot from either the install disk or the hard drive. The hard drive is still visible in disk utility as it always has been, but i am now unable to boot from it, let alone install SL.
Please help my iMac has been broken for months and i've been trying to fix it for so long and am getting problem after problem. Thank you!

Hi db2
That off the shelf MS-DOS / FAT-32 drive needs to re-partitioned GUID Partition Table / Mac OS Extended (Journaled) before you can install OS X and Startup your Intel iMac from it.
1. Boot from your original install or retail SL DVD and open Disk Utility.
2. Highlight the new HD in the list of drives and select the Partition tab.
3. Under Volume Scheme select 1 Partition and click on the Options... button.
4. Select GUID Partition Table in the drop down window and click OK.
5. Set the Format to Mac OS Extended (Journaled) and click the Apply button.
6. Once thats done, then you can do a clean SL Install, Restore from TM , your old HD or Bootable Clone.

Calling a method in the view controller from the component controller

Hi
Is there anyway to call a method in the view implementation from the component controller??
Thanks
jack

Thanks for all your replies. I want this kind of a functionality because Im trying to invove a DC (Child DC) from a Parent DC such that the Child DC's view is displayed onto the view container of the Parent DC. I have embedded using 'interface view of a component instance' in the Parent Window and am able to create the component and set usage though the onPlugDefault of the Child View.
But I observe that when i make a call from the parent, the flow is like this:
1. The wdDoInit of the Child Component Controller gets triggered first.
2. Then the wdDoInit of the Child's VIEW gets triggered
3. and THEN the onPlugDefault of the Child Component Interface View
What I had actually wanted was to Fire onPlugDefault where Im calling a method LoadData(), after which the Child DC's view must be triggered so it can display the fetched data.
What is actually happening is the view gets displayed, but no data is displayed in the view.
Right now I have just given a work around where Im triggering LoadData() of the COmponent COntroller from the wdDoInit of the VIEW.
Is there a better way to do this? I find it strange that I have to load the Data from the view.
Thanks
Jack

My trusty Mac LC no longer boots from the HD

I purchased a new Mac LC many years ago and it has served me well until recently when it would no longer boot from the hard drive. When I boot from a Disk Tools floppy, I get some limited success but do not ever hear the HD spin up. The startup chime also does not sound. When used as the boot disk and trying to use the installer option, the program can't find a SCSI drive, only the floppy drive. The 5V & 12V to the HD are right on and a new PRAM battery is installed. I can load and run programs using the floppy drive but that requires a lot of disk swapping. I tried substuting a tested Apple LC HD with the same results and now I suspect the problem is not the HD but is somewhere else. Any help would be gratefully appreciated. Thanks!

Thanks to Jan & Jeff for their quick response to my question. Here is some additional background information which may give you both some more ideas.
The original 40 MB HD was replaced with a 120 MB HD along with an increase in RAM to 4 MB sometime in the first year after I bought the LC. The 40 MB HD was installed in an APS (?) external SCSI box with its own power supply. OS 7 was just becoming available and Apple gave me a set of disks even though OS 6.x was in the computer so I put OS 7 on the external (40 MB) HD. Everything worked great for 20 years although there were periods of intermittent use when I used other computers for work, Internet, and e-mail. I powered up the external HD infrequently but it worked fine the last time I tried it some months back.
Then when I fired the LC up 6 or 7 weeks ago, it would not boot unless I turned the power switch on & off 2 or 3 times in succession then everything functioned normally. Then it would not boot at all even from the external HD.
Now, to address some of your comments and observations:
All connectors, plugs, SIMMs, and socketed RAM devices were removed, examined and replaced. All electrolytic caps showed no signs of leakage or swelling and the PWB looked in its original condition.
The +5, -5 and +12 voltages measured at the power supply connector were within 1%. When I originally thought I had a HD problem, I opened up the 120 MB HD and when trying to boot, the platter would give a slight twitch with no tendency to spin. A friend of a friend (a MAC serviceman) brought a couple of vintage drives SCSI over to try with similar results. The Apple HD I purchased was tested and guaranteed, although wiped clean. It has since been returned. As I said in my original question, the Installer on the floppy could not find a SCSI drive. In all of my efforts I could never get any of the hard drives to spin up.
Although I have a MacMini (OS 10.6.8), I still used the LC because for drawing schematics and floor plans, printing labels, etc., simple is better for me. Is there any hope that I can get my LC working again?
Many thanks for your help and suggestions. len-35

Installing Windows 7 on my bootcamp partition (mid-2009 mac book pro with mountain lion) My computer won't boot from the Windows 7 Install DVD.

Hello,
I have been trying to install Windows 7 on my macbook pro (mid 2009, MBP53). I have successfully created a bootcamp partition using the assistant. When the computer tries to boot from the windows 7 install dvd, the screen is just black. The dvd spins for a bit, then stops and the computer is just black (no blinking cursor).
Any advice would be very appreciated.
Thanks.

What kind of an install DVD are you using for Windows?
You can use any DVDs that are hardware specific. Only the full non-hardware soecific DVDs work on the Mac.

Help needed on startup. My computer will not boot from the CD drive!!!

Problem with iMac G3 333, the Message on the screen states: "The System Software on the starup disk only functions on the media, not if copied to another drive." Like a fool, I copied the system folder from the original system software 9.2.2 on to the iMac. System disk which is not a complete system folder when used on the computer. I have searched the Internet, but can not find an answer. I have tried everything, holding down the C key, "Delete, Opition, Apple key, shift" holding the mouse down on startup, various combinations of other keys, etc. The CD starts to spin, but the computer switches to the hard drive and the message above returns. No matter what I try I still can't boot from the tray loading CD drive. Is there any Firmware code that I can use. I know how to access Firmware on the Imac and can boot the iMac using Firmware, but I don't know how to use Firmware to boot the CD drive which I need to do so I can reload the original software. CAN SOMEONE PLEASE HELP? Thanks, Jim

Yes, I have tried both System Softwares a number of times. The C key will not boot up the CD drive and the harddrive always boots with the original message. I need to get the CD drive to boot so I can reloaded tge original software. Do you know anything about booting the CD drive using Firmware? Jim

I can't boot from the windows cd with boot camp

I got Vista up and running via boot camp but now I have a problem that could cause some issues. How the **** do you boot from a windows cd with boot camp!?!? When I stick in the windows based CD (could be the vista install CD -after vista's been installed of course- or a Windows home server restore cd) and hold down the option key I chose to boot from the CD in the menu then the screen goes black as it should and then it says press any key to boot from cd or dvd..... It gives me 5 seconds to press a key and then it conintues to boot into Vista. The thing is when it asks me to press any key I press any and all keys on the keyboard and I get no response and it just boots into vista. This can be quite a problem, what if I need to restore vista via the install CD? I can't chose to boot from it cause everytime it asks me to none of my key presses register. So everytime I have a problem I won't be able to restore or even diagnose it, I'll just have to reinstall vista? I don't think I can even bring up the safe mode or anything like this. The keyboard won't work until I reach the password screen of Vista. I've also tried plugging in a USB keyboard to it and it still doesn't work. So basically I need to know how to make the keyboard work before Vista loads.

Ok, well I just tried booting from the windows cd and it seems that I lied to ya It seems that you can boot from it. Although I only took it to the point I was comfortable with. The boot resulted in it asking me to install windows and I didn't see any partitions listed or anything, so I chickened out (so to speak) not wanting to take the chance of my Leopard installation getting screwed up.
It's been a quite some time since I used the Vista boot disc and can't really remember how it went when I used it in conjunction with boot camp beta. Sorry can't give you anymore information.
