Hi all,

I'm currently working on a pc that belongs to a friend.
I've replaced the video card beqause the old one was toasted.

Now i got screen but when the pc boots up i get this error :
Award BootBlockBios V1.0
Copyright (c) 1998 Award Software, Inc.

Bios ROM Checsum error.
Detecting floppy drive A media...
So i figured that the bios checksum is corrupted (As far as my knowledge goes by i guess it would be a short circuit in the vga card).

Anyhow, i need to flash my bios chip.
Since it does not boot and the only message on the screen is the error i described earlier in this post. I cannot retrieve the bios string by running some app.

The specs i have so far:

1. The mainbord is a chaintech (I guessed it beqause the logo on the Northbridge is from chaintech).

2. In height order : 1x AGP, 1x AMR (Modem port), 5x PCI, 1x ISA.
3. 2 USB 1.1 ports.
4. Prolly VIA VT82C686A chipset (Southbridge).
5. Socket 370 Proc.
6. 133 MHZ BUS (Since all the RAM modules are 133 MHZ).

For further specs just look at the pictures.

Mainbord :

Chipset :

BIOS/CMOS chip :

Stickers on the bottem of the ISA slot:

Can anyone help me finding the correct mainboard manufacturer and/or the serial number of this board ?

Note that the CMOS battery is just on the side of the CPU socket.

Probably based on a 694x chipset.

Model number may be 6AJA4 but this should be equipped with 686B Southbridge. MAybe your board is an OEM version as there seem to be an additional IDE controller is missing as is a second flashrom (see solder pins).

Very sad the Flashrom sticker is gone - there's often a small white sticker on top of the Flashrom with a model number. Sometimes it is located near the flashrom.

What's printed there between the PCI slots?

Check around the edges of the board. Perhaps there is more information to be found.

Thanks.

The text says that this motherboard is year 2000 compliant and FCC approved. There is no FCC number on it.

On the left side of the ISA slot there is a small number.

Is the board installed in a branded system?
-> Name and model number of this branded system needed, may help to identify the model number

Please test the memory sticks, use only one memory stick at a time and check whether the system is booting now instead of operating in the emergency bootblock Bios mode.

What is written between the 2nd and 3rd PCI slot counting from the ISA slot? Something in white ink, can't make heads or tails from it.

There's an 6AJR4 with raid controller as well.

I guess those are the raid ide and highpoint bios locations.

I guess it isn't working now so all that could happen is it not working afterwards either. Just make sure you line up the cmos chip the right way when placing it back. I guess you will be hotflashing it?
