I am not sure that corrupted BIOS chip whether compatible with that motherboard or not.Im providing the link to the both motherboard model's page. Also I don't have floppy drive I have to use usb disk to flash the bios the both are compatible to flash give me a step by step instruction to flash the corrupted chip.I assume you downloaded the most recent update file--P5GC-MX-ASUS-1333-0413.zip--and flasher file--AFUDOS236.zip--and extracted them and copied them to the flash drive. ROM.)Then use NOTEPAD and write in it a single line exactly as: AFU236U /i P5GC. Now it's possible part of the update process will ask something like 'are you sure you want to do the update' which of coiurse will require a keyboard response. " but if none of the above applies then it sounds like the motherboard or maybe some ports are damaged. Also all the components are okay I have checked all these with another pc.
I've never had to try anything like that so am unfamiliar with it. It looks pretty good except the win98 dos files it has you download contain files that aren't compatible with doing a bios upgrade.You'd have to delete all the 98 files except for msdos.sys, and Your example will work fine so rename it from P5GC-MX-ASUS-1333-0413. Run notepad again and open the file on the flash drive. It may or may not work in your case but give it a try if you are asked the 'are you sure' question. An file runs on its own so you shouldn't need any keyboard input. Also I heared somewhere that there is another method to do the same called "hot swap"But I think its kinda risky since I have another p4 945 sis chipset asus mother board but im not sure that my bios is compatible with that motherboard or not.all I knew after looking both chips that both are 4mb bios i don't know about voltage.please suggest me which option is best for me.should I use hot swapping method or not?If that doesn't work then we'll have to find a flasher that is compatible with the bios chip and won't pause to ask questions. I had disconnected the power chord during jumper reset. Or any alternative ideas will be greatly appreciated.Since you appear to have the necessary boot files we can try setting up the flash drive to run the update by itself. So the only files on the flash drive should be the two hidden dos boot and msdos.sys--as well as command.com, afu236u.exe, p5and will run on it's own and give the command to do the update.

If neither a USB or PS/2 keyboard works then you're kinda screwed. Thanks DAVEINCAPS for you quick reply.'Hot swap' when doing a bios update is when you boot up the computer with a good bios chip and then with the PC still running you remove the bios chip and put in another one to program.
Sometimes it'll take a minute or so for an error to pop up. When you use the jumper to clear the cmos you need to have the power cord disconnected. The chip you swap in has to be exactly the same as the original one and obviously it has to be socketed and not soldered directly to the motherboard. Post back a link to the bios update you want to install and I'll download it and take a look and see if I can set it up that way.
"Yes I have prepared the bootable usb with the three files I was able to enter into dos .
There cursor was blinking too but the problem was to enter the command and since keyboard was not detected I couldn't be able to flash the bios.
I was following this one link to flash bios using USB drive: you can prepare a batch file to run the command then there is a hope that it can be done.
