procedure to use a flash writer

Post by Sayang »

Hi lads,

My bios is screwed-up :cry:
However, I have access to a flash writer :D

Q: I dump the RV bios file (256ko) directly to the flash?

Thanks.

while i'm looking for more info ....
if you can use a flash writer, you must be able to extract your bios chip.
if you can get access to another bp6 board, you can, ....
boot the good board..
take out it's chip..
put in bad chip..
run bios flash program...
all better bow

The pdf says:
Remove the BIOS ROM and manually reprogram it on an EEPROM programmer.
It's not too much helping though

try the auto-boot load options mentioned first.
then, if you're going to write the chip in the writer, it won't matter how you do it.
if you can, you can re-do it if it's wrong.

Hi Sayang,

If you have had a bad BIOS flash, you can start your BP6 with an old ISA video card and get a rudimentary display. From there you can flash the BIOS again with a boot floppy in the usual way.

I have done this before on my BP6 when a flash went pfffft. Nowadays I always keep an ISA video card in case it happens again.

Indeed my ROM checksum is incorrect.
I can start and flash without an ISA card: my AGP card works.
But flashing fails writing for the first 14 blocks of flash using awdflash (see my post here: http://www.bp6.com/board/viewtopic.php?t=2119)

Do you think the ISA card solves the flash write error?

I can't wait for other's input to I tried:
Great... it worked without my AGP card, I get rid of the write errors
and without any graphics card at all!
I used the autoexec.bat to automatically flash at boot.

You can throw away your (old) ISA card :wink:

I did throw away all my old ISA video cards...along with most of my floppy drives. Now I know to keep some of that "vintage" stuff around because its so old that in some cases you can use it to as backdoor access when the front door is locked.

Personally I hate flashing BIOS. It scares my hair grey.
There are *almost* no bad BP6s. There are mostly bad caps.

No BP6s remaining

I know what you mean. I had to buy a box of floppies last time I wanted to do a BIOS flash. I've removed the floppy drives from both my PCs, but still keep one in the cupboard along with my ISA vid card.
