I never cleared the cmos with the power on. Sorry i didnt make it clear, but yeah i always made sure the power was completely out. I left the battery out last night too, but still no change. All cables are on right, and I'll try taking out all the cdrom and cd when i get home. I cant get into Bios (pushing del key). all i get is two beeps and boot block telling me that there is a Bios Rom Checksum error (again, sorry i wasnt being very clear).
I think it might be pretty much stuffed. I'm tempted just to go to the store and buy another one as they aren't too expensive and probably not too much of a price difference from getting a new bios chip and having to wait for 2 weeks while it gets delivered. But then again maybe i should just be patient and save myself some money.
Hmm, could it be due to bad RAM? I'll try swapping it with my brother's and see what happens. It's kind of ridiculous that they give the same generic error message for a multitude of different problems, someone should fix that.

K7N2 - Bios Checksum Error - But wont load program to flash bios

Hi there, my computer restarted itself due a problem with windows (kernel dll or something arather), since then it wont boot at all, beeps twice and says Bios Checksum error.
Now i understand this means the Bios is corrupted and i need to re-flash it. I looked at instructions on how to do this and followed them to the button. However, it wouldnt load a boot disk at all so i reset the Cmos using the jumpers.
After reseting it would now read the disk (i can hear it make noises) but it would only get as far as starting to load the award flash program, i.e. it just says "Starting..." but then the disk will stop reading at it will just hang then doing nothing.
I've tried numerous disks and numerous bios version numbers (but obviously the right ones for my motherboard: K7N2 Delta series Ms-6570), and i've tried using different types of bootdisk all with the same result.
Is there anything else i can do? or is it pretty much screwed and i have to take it back to the shop i bought it from and request a new bios chip (technically its still under warranty, as its only 10 months old but would this be covered with the warranty?). I can foresee taking it back being a huge hassle so if there is anything i can do to avoid this, it would be greatly appreciated.

URGENT HELP!! BIOS Checksum Error, Floppy?

When I boot up, I get a error saying "BIOS Checksum Error"
and it asks for a system floppy disk
I cannot get any further.
I tried flashing the bios, but this does not work.
Please help!!!

oh, yes thats what I meant.
sometimes the it would not read the floppy
somtimes it would hang while booting the floppy
sometimes I could get far enough to run the flasher utility but it would hang
finally I was able to get far enough to flash the bios, then everything worked fine.
I guess it just got corrupt some how.
I set my boot floppy to load zero drivers and do nothing.
and I set it to run the flash on bootup.
I think there is a time limit or something before it hangs and gets stuck.
I also moved my ram from ddr2 to ddr1, that also seemed to help it get farther.
I just kept trying for like two hours until it worked.

SRW248G4P - (!)Loader Binary checksum error - ERR Runtime Loading Fail - System Halt.

We have this 48 port switch in our engineering department, and it basically stopped passing network traffic.
When connecting to the Console port and power cycling the switch, this is what I see:

I've tried to update the "SRW224G4P_SRW248G4P_image_v1310.bix" file using Xmodem download, but since I really wasn't sure how to use this boot loader tool, I haven't been successful at doing that, nor do I even know if that's the solution for the problem that I'm having.

I'm guessing that I'll need to contact Cisco tech support, although at least through their web site, they make that nearly impossible to accomplish.
Does anyone have any suggestions on what may have happened to our switch and what I should do to recover? Of course we're about to start a time-critical round of product testing, and without this switch, I'm dead in the water. And it's not like we have a spare 48-port PoE switch lying around.

Hello,
I got the same issue. After downloading and uploading the firmware, I got the following result and all LED on the switch are glowing. Could you please help on this issue? Where can I find the right firmware. I also have Image loader 1.0.1.

HP Model #A6000n Bios Checksum Error after Bios Update!!

I performed the Bios update posted on Hp's website...After the re-boot, all I get is this error, "BIOS Checksum Error," and then the black screen looks for a bootable disk on floppy (this computer has none), then, it looks for a bootable disk on the CD drive. Now, I have talked to HP support and they say I need to order the recovery disks. Can someone send me a bootable file that I could burn to CD for this model machine and get it up and running?? I have an older machine here that would allow me to make a bootable CD but, I have no idea where to locate some kind of BIOS update and or, bootable file to flash the BIOS. I am so mad that HP has wanted me to purchase this CD recovery program just to get back into Windows Vista. But, I am not sure what to do since the BIOS update must have been corrupt when I flashed the ASUS motherboard. This computer is my Aunts and she failed to make back up restore disks and now I am lost as to getting this thing up and running...Please help!!
Thanks!
This question was solved.
View Solution.

Like I said, if you have a floppy it is easy, especially since the computer doing the floppy is XP.OK, here we go.
1) place floppy disk in drive
2) open My Computer and right click on the floppy drive
3) pick format from the menu that pops up
4) put a check mark in the box next to the "Create an MS-DOS startup disk"
5) click "Start"
6) when completed copy the awdflash.exe to the floppy
7) right click on the BIOS file from HP
8) move the mouse cursor to 7-zip and then click on "open archive"
9) double click on the folder icon in the new window
10) right click on the ROM file - in this case 513.rom
11) pick "copy to" from the menu and browse to the floppy
12) when that is complete, the floppy should be ready to work
13) Move the floppy and ribbon cable to the Vista computer. It does not need to be mounted but make sure it is not touching anything metal ( a stake of books will do fine) and connect the ribbon cable and power to the Vista computer's motherboard and power supply (of course this is done with both of the computers off and unplugged)
Now ready to go on the Vista computer. When the power button is pressed on the computer, there will be an HP splash screen come up. From that screen press the "Enter BIOS" or "Boot setup" key as indicated. Forgot to ask if this screen comes up in previous posts. If this screen does not show then this is going to be much harder.
When in the BIOS, look for boot order and then set it to boot from the floppy first. Save choices to exit.
14) Reboot - should end up with a flashing cursor in the top right corner
15) type AWDFLASH 513.rom /py/sn/cc then hit Enter
16) when and if it completes power down and remove the floppy drive from the computer
That should do it. If it does not work or there are problems come back with an explanation of what did happen.
Of course, doing all this at your own risk. I am just trying to help.

IPhone will connect to network but wont load any internet pages.

OK, I have an iPhone (1.1.1) and an apple airport graphite base station which is connected to a D-Link G604T router.
iPhone will connect to the airport but wont load any internet pages. My iBook works fine on the internet when connected to the airport.
Any ideas?
Thnanks.

Daniel Langer,
Make sure the graphite base station is configured as a bridge, and not assigning IP addresses itself if the D-Link is doing DHCP.
If it is acting as a router, you will have NAT occurring twice, which can have a variety of issues.
Hope this helps,

Reinstall OS X, either from disc or a recovery partition. You don't mention which version of OS X you're running so I don't know which it will be.

Bios checksum error

have two kt7 pro motherboards on differnet machines and both are having exactly the same problem. I originally had a problem wiht booting my hard disk, so I tried to boot from an old win 95 HD and put my win 2k HD as a slave. This is when I stated to get problems with my motherboard. During the POST, I get a Bios Checksum erorr, cannot find Drive A. At this point the machine stalls with the diagnostic LED showing that I it cannot find the memeory. However, I have tried numerous banks of memeory so I am confident that this is not the problem and have tried resetting the bios (by removing the battery and moving the jumper). This is happening on both machines, with or without any other hardware connected.
Please can anybody shead some light on this frustrating problem.
Thanks
Aaron

Hi!
I don't want to insult you, but...
Are you sure you haven't connected the floppy drive ribbon cable upside down. (Remember, the lump s/b directed towards the bottom on floppies, i.e. -----¬_------, not ______¬______ like on IDE devices.
Could try disconnecting the floppy drive (including power) and disabling 3.5" floppy in BIOS.

Itunes installs but wont load up

I have installed itunes 9.0.2 64 bit on windows 7 64 bit computer. It wont load at all. itunes.exe*32 starts up in the task manager applications then quickly disappears and nothing more happens. I have tried downloading again, and removing all apple applications and registry refs then reinstalling but that doesnt work either. I have tried turning off virus programs, checking computer for malware and spyware.
I dont know what to do next. I just cant get it to load. It worked prior to the itunes 9 upgrade. but now i cant go back as I have uninstalled everything.
I was dreaming of an iphone - I guess that is out of the question if I cant get the software to work at all

I do use norton 360 so maybe some vodoo there?
Possibly, although I tend to associate a Norton-related (generally speaking, "firewall-related") error-message-free iTunes launch failure with an iTunes.exe appearing in process manager and never going away (rather than the quick flash of an iTunes.exe that you're seeing).
Could you check something for me, please? Try to launch your QuickTime Player. Does it launch properly, or do you get odd things happening when you try to launch that too? If odd things happen, could you describe them for us?

Dell 7520 (15r SE) BIOS checksum error

Hi everyone,
After sucessfully upgrading my laptops BIOS from A09 to A11 yesterday it booted normally but today it just beeps (single beep every few seconds -> ROM checksum error...).
Is there a recovery method like the Phoenix Crisis tool or such to recover a broken BIOS or can I flash the BIOS using an SPI-Flash programmer?
Thanks,
Jakob Riepler

Iphone connects to wifi but wont load any data

my iphone will connect to my wifi network with a good signal but when i open safari, check weather,stocks etc. it wont load. in safari it says it cant connect to the server and in weather, stocks etc it says update failed. It just started doing this yesterday and my wifi worked before. Also my internet is working. Please help this iphone isn't even a week old!!!
PS i can connect to other wifi networks but not mine

wonder if you could perhaps help me also with a similar difficulty ?
I have the itouch and I am having a Wifi issue. Is there a particular kind of combination setting that perhaps I am not doing. What I mean is when you go to wifi settings. There is DHCP , BootP and static at the top of the page. Then at the bottom, we have off, manual and auto. Also in between all that there it displays Ip address , subnet mask, router, dns, search domains and client id.
What is a dns ? I would love to know and even better how do I get this thing to work, which did until three days ago.
Thank you in advance

BIOS checksum errors

I am running Fedora 14 on my ThinkPad SL500. The dmesg command indicates that there are checksum errors in the BIOS:
$ dmesg | grep checksum
[    0.164256] ACPI Warning: Incorrect checksum in table [SSDT] - 0x4E, should be 0xDD (20100428/tbutils-314)
[    0.167894] ACPI Warning: Incorrect checksum in table [ATKG] - 0x82, should be 0x53 (20100428/tbutils-314)

[    0.209744] ACPI Warning: Incorrect checksum in table [SSDT] - 0x4E, should be 0xDD (20100428/tbutils-314)
I have updated the BIOS to the version of 12/16/2010 and then reset the BIOS settings to the manufacturer defaults and still recieve these warnings.

welcome to the forum!
are you having any issues with ACPI events like suspend or hibernate?   if not then i wouldn't worry about it at all.
even if the checksums are incorrect it's unlikely that these are causing any problems in your system.   if you are having issues though please report exactly what you're experiencing with a description of the steps necessary to reproduce the issue(s).
