Archief - biosflash -> pc boot niet meer

mijn pc boot niet meer na biosflash
verhaal: download flashmenu van abit (voor mijne nf7) en ook de nieuwste bios, dan doe ek update from file, paar min wachten....
update succesfully en em vraagt om te rebooten en dat doe ik
maar dan start de pc niet meer op, fans draaien, maar bij opstarten krijg ik ook niet het bekende 'biepje' en geen beeld, scherm blijft in stand-by.
ken ook 'iets' van hardware, alles wat gecontroleerd, cmos clear & batterij eruit, maar nog altijd niets, dan ook proberen te booten met opstartdiskette en cdrom van xp. zelfs met alleen het noodzakelijke (ram, mobo, cpu, graka)
en al deze mogelijkheden door elkaar, maar nog altijd niets
kheb niet veel goesting om ermee naar de winkel te gaan en die paar dagen kwijt te zijn, dus vraag ik et hier
wat kan ik nog doen?
specs:
Abit nf7 (rev 2.0)
amd xp 2400
512 ddr corsair vs
abit fx 5200 128mb
seagate 40gb
cdrw (lg denk ek)
diskette

merci op voorhand

ps: stond geen virussen, spyware,... op pc

mja gij zegt mss succesful mer ik vertrouw het ni, kan goed zijn da uwen bioschip nor de zak is

hotflashen

@vinteg: ik zeg nie succesfull, mijne pc zeg da, kgeloof die wel nie altijd mo kom
en zukke bioschip kost da veel? :/
@Mithrandix: hotflashen? kunde mij ff uitleggen wa da is?

thx vo reply

Hot Flash
Doing a hot flash may seem radical, but it's nothing more than flashing the bad chip on a different (working) motherboard of the same make and model.

Here's one way to do it. (This procedure is not approved by anyone. While it worked for me, do this at your own risk.)

On a working computer (hopefully with the same motherboard as the board with the bad chip), insert a floppy and make a DOS boot disk by typing
=> sys A: at the DOS prompt. This will put the files needed to boot into DOS on the floppy so you can perform the flash in a clean environment (meaning not in Windows).

(Update: you can also download the files to make a DOS boot disk for your version of Windows from http://www.bootdisk.com/) On the same floppy (or if you can't fit it on the first disk, use a second floppy) copy the flash utility and BIOS bin file to the floppy disk.

I was able to get everything on one disk.
For my Abit BX6r2, these were the files needed to flash the new BIOS:

awdflash.exe (the utility that executes the flash)
Bxr_kh.bin (an old, but workable BIOS version)

NOTE: The Bx6r2 is an older board and while the information stated above is correct for that board, many of the recent boards come with new BIOS Flash utilities, which include a DOS-type interface to flash the BIOS (usually something similar to DrDOS). See your motherboard manufacturer's site and read the BIOS flashing instructions. If your board manufacturer has a DOS utility included in the flash setup files, you won't need to do the "sys A:" command, just make a floppy of the BIOS tools, the flash utility, and the proper "bin" file that you are going to flash. Do not try to run the BIOS flash from a file on your hard drive, or from a command prompt from within Windows. Use a floppy with DOS or an equivalent. If you try to flash from a file on the hard drive, bad things may happen!

Whatever DOS / BIOS flash setup you need to use, the next steps are as follows:

1. Shut down the working computer and carefully remove the CMOS chip, then reinsert it loosely enough that you won't have to pry on it too much to get it out a second time. See that it is seated well enough that all pins are in contact with the socket. Take care that you don't bend the pins and play it safe by grounding yourself with a wrist strap to prevent static discharge from killing the CMOS chip.

2. Boot the system with the DOS or Flash Utility disk.

3. With the computer running, CAREFULLY remove the good CMOS chip and replace it with the bad chip. Observe the orientation of the chip when you remove it. There will be a notch in the top of the chip to show you where "pin #1 is." Make sure that this indicator is in the same direction when you insert the bad chip. This should be done carefully. Did I say carefully? Should I say it again? Don't let the pins on the chip touch anything but the socket (and in the proper place.)

4. Now that the bad chip has been installed, from the DOS prompt, type your flash command - for the BX6r2 with the BIOS file I used, it's:

A:\ awdflash bxr_kh.bin /py /cc /sn /cd

Now, hit return to get it started and follow any instructions your particular BIOS / flash utility requires. (Read the README file that comes with the flash utility for more information.

The flash procedure will take place and if you're lucky and soon you'll be prompted to restart the computer. DON'T RESTART THE BOX, SHUT IT DOWN. Use the power button or yank the wall plug if necessary.

When the computer is shut down, remove the CMOS chip. Replace the newly flashed chip with the good (original) chip and reboot the box (in normal - Windows - mode) to make sure the good computer still works.

Now you can try your newly flashed CMOS chip in your broken board. If the gremlins that live inside of all electronic parts like you, you'll have fixed the broken board. If not, you can always buy that new CMOS chip.

There are some variations on this procedure depending on the outcome. I read about a guy who couldn't get the DMI section of the chip to clear until he shorted the right side pins of the chip to "clear the memory." Interesting reading here.

All of this is well and fine, but I had a bit of a different situation. I didn't have another computer with a BX6r2 motherboard. I did have a Abit BH6 (different size CMOS chip), an Abit AX5 (not a chance from the data sheets), a bunch of even older boards (nope), and an Asus P3B-F. Hmmm, I wonder.....

The Asus uses a Mosel Vitelic V29C51002T-90P chip and the Abit uses a Winbond W29C020. After going through the data sheets, it appeared that the chips were pretty similar. I figured I had nothing to loose but an already unusable chip. I went through the procedure without a problem up until I started the flash using the Abit Awdflash utility on the Asus board. No good. The utility wouldn't recognize the board and stopped there. Being half-way there and not ready to give up yet, I tried using the Asus Aflash utility with the Abit bin file. It complained that the BIOS was not the correct one for the motherboard, but gave me the option to flash it anyway. I gave it a try... and was then told that the flash was successful.
It didn't lie!
I now have one BX6r2 that has been reclaimed from the dead.
Amazing!

Now, I would be remiss in my duties if I didn't warn you that this was a somewhat foolhardy venture and that if you have any sense, you'll order a replacement CMOS chip and wait for the replacement chip to arrive. However, if you're like me and throw caution to the wind on occasion, you just might find yourself hooting and hollering with that great rush that unexpected success brings.

I hope you have the same luck that I did!

Corrupt Bios

Here is a classic problem with Younger NF7 mobo's.

On some young mobo's especially "young" ones, people have ran into trouble when they started over clocking and ran into a big problem that their system now does not boot and can't be resurrected. There is no video signal at boot time? Fans turn, Hdd spin up, red & green lights are on on the mobo....tried clearing CMOS but it does not help? Any ideas what to do next?

Answer to this as described above is you have hosed your BIOS chip. Most over-clockers will have encountered this in Ocing NF2 boards. It's a well-documented problem of the NF2 chipset saving new BIOS settings via the NB memory - which corrupts the data when FSB is "out of spec". It's generally a problem to younger boards but as they get "run in", they mature and the problem disappears. As I have said before, because of this flakiness its a good idea to have another bios rom and hot-flash the old one if this happens to you, if your into Ocing then a backup spare Bios rom or a Bios Saviour will not go amiss.

das van u mobo
