China DOS Union

Just discovered something strange:
I can't find the BIOS chip on my motherboard! (The one that's usually the removable BIOS chip)
I saw that other computers have it

My motherboard is an Intel 815 (Diamond 815e, CS65-EC)

In the afternoon, my colleague's computer broke down and went for repair. As a result, the BIOS rom was broken and couldn't enter the BIOS!
(Error message as follows:
BIOS ROM checksum error
detecting drive A
INSERT SYSTEM AND PRESS ENTER)

Came back and checked the book, saying that the BIOS chip content was broken and needed to be rewritten, so I moved the computer home and prepared to use my computer for hot-swapping and rewriting... But then I remembered that my computer couldn't find the BIOS chip!

Is there anyone who knows to say where it is?

The red circle is the BIOS chip.

The original picture for problem solving has been deleted.

Hey! Brother fastslz seems to know everything!
Got the screenshot so quickly!
Thanks a lot!
Oh, is that the firmware?

Can it be pulled out and then inserted again?
This one seems to be different in size from the BIOS chip of my colleague's! Can't insert it!
His is a Qisda U8569 motherboard, the BIOS chip is very large (mine is very small)

It seems it's not possible?

Firmware chips of the same type can be hot-swapped. There are just 2 common types of firmware chips. Look for other friends who have the same type. Be careful of short circuits when hot-swapping. It's better to make a hooked hot-swapping tool with tweezers for safety.

Posted in 2003.

Post a BIOS emergency recovery disk image for safety.

Usage:
Copy to a floppy disk using hd-copy.exe or wiimage, and also copy your BIOS file (make sure it is the file for the motherboard and is intact) renamed to: bxb1.bin to this disk (suitable for Award BIOS update and recovery in case of failed flash-------the premise of recovery is that the bootblock is not damaged..), the advantage of this disk is small size and fast running, reducing the time of worry.

Hear 4 BEEPs means successful repair, if not at ease, wait for 5 minutes from reading the disk.

If necessary, AWD802.EXE can be replaced with a new version (preferably provided by the manufacturer), but the file name remains AWD802.EXE.


Please share your feelings, encountered problems and suggestions after use!!!!!

It's a good sign that you still know to ask for a floppy disk.

1
The pinouts of the BIOS chips of the two machines are completely different, so they can't be inserted.
I can only give up and ask the seller to return the chip (I really want to do it!)

2
Although there is "detecting drive A", it's just a useless detection
Put in a good floppy disk, and it doesn't read it.

The monitor displays "INSERT SYSTEM AND PRESS ENTER". Press Enter. If you use my disk to read, it can be repaired. Otherwise, you need to find a host with the same chip for hot - swapping or a programmer.

Generally speaking, if there is still a prompt for drive A, you can boot into pure DOS with a floppy disk and directly flash the BIOS, which usually works.

Specifically:
1. On a normal computer, use SYS A: to transfer DOS startup to the floppy disk;
2. Copy the Award BIOS flashing program and the motherboard's BIOS file to the floppy disk;
3. Insert the floppy disk into your computer, restart, and flash the BIOS.
