Question about Biostar NF325-A7 Motherboard

Can't seem to flash the BIOS

I'm having a hard time trying to get my bios working again. Originally I had flashed the bios with what i think now is the same bios that it had only I had done it from windows, which now I know was a mistake, and 2 that i had selected AMI instead of award which is what my bios is. Which btw is a BIOSTAR NF325A7 V1.1 .. Anyways.. so now I get the Boot Block error, saying BIOS ROM checksum error.

I have been using a DR DOS formatted floppy with AWDFlash 8.82 and the bios which was originally saved when I had done it from windows which is named

If I proceed through with AWDFLASH. I can get it to go [still takes a minute or so to start] But, once it starts to write the BIOS it will stop and say FLASH ROM IS WRITE-PROTECTED. <-- Now I've read that this is because of a write protection setting in the BIOS. So I'm really stumped.

I have actually gotten it to flash once. It actually said flash complete. But when I rebooted I got the same bootblock error. So I pulled the battery out and set the jumper to clear the CMOS. I left it there for a couple of hours hoping that it would bring it back. IDK, I read somewhere on some site about having to leave it there for like 24 hours or so for it to be effective. Anyways case in point. I'm still at the same spot and want some help.

Have it done it right just haven't finished it somehow or have I not gotten anywhere?


All I have connected is the PS connected to the MOBO, one RAM module, The CPU and Heatsink seated and working; and a floppy drive.

BTW I'm aware that there is a BIOS upgrade function in the bios.. however I didn't know that prior to flashing and now I can't get there anymore.

This probably isn't what you want to hear but I would recommend just contacting the manufacturer and getting a replacement at this point. You will be spending a lot of time and be very frustrated in the end. Trust me.

Sony vaio vgn-s2hp did a restore - cannot find operating system message - replaced drive, same message. Bios is corrupted, how can I fix this?

1st-What O\S (win-xp, vista, # 7,etc.) did you "RESTORE" ?
2nd-Why did you mess with the BIOS. ? Did you understand that the BIOS is the INSIDE\PHYSICAL part of the laptop and NOT the Operating System [O\S] Windows_xp, vista, #7 etc.etc.
3rd-That "cannot find operating system" could be something as simple as the BIOS was RESET by something as a 'glinch', electrical short, suddenly turning off ( not that you did it! ) of laptop , lighting while you were working ( ALMOST ALWAYS... when the computer is writing to hard drive [H\D] with laptop
The BIOS could not see the H\D because is was changed by sudden electrical surge.
That you replaced H\D, you will have to REINSTALL the O\S again.Because I will assume that you brought a DIFFERENT type of H\D [ maybe something with more GB?, different model H\D ]

I had tried to flash my Gb-k8vt800m board using @Bios and got a bootblock lock up. I had saved the original bios to a file on my desktop prior. I now have that hard drive as a slave in second identical...

99.9% of all computers will never need the bios flashed.
This is printed on the bottom of the gigabyte web site.

Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in system malfunction.
The problem with your computer has nothing to do with the hard drive. You need to repair the bios. There is a way to flash the bios without booting into Windows. I'm pretty sure that a floppy drive is involved. You're going to have to figure out how to flash it back to your original bios that you have saved on your hard drive without booting into windows. There is some info on gigabyte web site about flashing bios. My internet connection is bad today and I can't download very well from that site or I'd give you an address.

Also remember that when you flash the bios all the settings in your bios reset. You should enter setup and click on the "load optimal defaults" Then you need to make sure date and time are right. Need to set boot options. Check that the clock ratio is right for CPU. There are a lot of options in there that can be keeping your system from booting it isn't necessarily a failed bios flash other than not getting the settings right after flashing.

My pc partially doesnt work. when i press the

I would start with a new bios battery first.

There is absolutely no need to reformat a hard drive for a bios issue.

I would also hold off on flashing bios just yet although that could be a later option.

Just take note of the battery position IE positive "+" up or down.

Dead gigbyte GA-81945 Pro ,, Help with compatabilty issues!

Hi bob_snz:
If the bios is corrupted, as it seems to what happened, you may be able to fix it.
So, what you can do to restore this board, if the bios is replaceable is to buy a new bios module for this board. Be sure to get the exact model marked on the board with the version #.
The data is still on the hard drive. So, what you can do with the hard drive, if you decide to get a new board instead of trying to fix this one is to put the hard drive in another computer and set the drive as slave. Next is to copy your data to a DVD (s) or another hard drive.

In this case you have a couple possibilities. Try to fix this board with a new bios module (if it is removable).
Unplug your hard drive. Use another computer to download the correct bios flash version. Use a floppy if available, to try to flash the bios again. The floppy would be self boot to access the bios without booting the computer. Usually the floppy only boots what is necessary to get to the bios firmware and loads to the bios flashing it to the correct firmware.
Since the bios may be corrupted, this operation may not work, but may be worth a try. If you do not have a floppy on the computer find a floppy from a friend or if you have one, install it and proceed.
Again, it may not work if the bios is completely out of commission.
Hope it works.

Via epia-5000 motherboard with Award BIOS

Couple of things you have to do...first, flash the bios with EPIA0207.BIN (using awdflash.exe). Likely you're going to have to pull that drive and reformat it, there's a great in-depth tutorial here (includes where to get the files):

I noticed that after flashing the BIOS I had to pull the CMOS battery, move the jumper on J10 to 2-3(check the corresponding manual for your board), let that sit for about 5-10 seconds, move the jumper back to 1-2 on J10, and replace the CMOS battery. As soon as all of that was done...I was in, no password required.

CMOS battery drains after one startup. Gigabyte GA-K8N-SLI

OK lets see here! Make sure your CMOS jumper is set properly on the board(Set to Normal) or Did you configure your bios after flashing the bios(going into bios and Load Optimized Defaults!)? or I don't think it would be another device in the system, but you can try troubleshooting by starting up with only what you need to run the machine (Mobo, memory harddrive, keyboard and mouse) then one by one adding devices back! or Did you have problems like this b4 you flashed the bios! Try flashing the bios back to an older version! post back if anything new or if i'm way off! Good Luck regards, babb
