AOpen AK77-400N BIOS ROM checksum error, please help!

[eskEMO]

Hi,

My girlfriend's sister put the wrong BIOS download onto their computer and now we get this error when booting up:

Award Bootlock BIOS v1.0

BIOS ROM checksum error

Detecting floppy drive A media...
INSERT SYSTEM DISK AND PRESS ENTER

I need help creating a system disk and then probably help from there.

What do I put on the floppy disk to make it a "system disk"? Please help, I'm completely lost and my girlfriend's mom needs her computer back as soon as possible.

Thank you in advance,
Jesse

Get drdflash.exe (bootdisk creator, search with google or others for links) to create a bootdisk on a working computer.
Then you need the Bios file and a flashprog, both should be supplied from Aopen.

Hi again,

I tried doing your exact directions and it didn't work.

I got the message:

"Invalid system disk, insert disk and hit enter"

or something of the like. Any ideas?

Doubleclicked on drdflash.exe to create this bootdisk ? Does this Botdisk work in your other computer ?

It may also be posible the Bios is further damaged or it's not able to adress your Floppy controller because of different I/O chip the other Bios was designed for.

Ohhhh, I have to double click on drdflash.exe while it's on my working desktop to create the floppy as a boot disk? I'll try that.

Thank you SO much for the help, Denniss. The computer is working as well as it was before, now. Thanks again, mate.
