Re: Extract BIOS from legacy DELL 1764 flash.exe
Hi
Yes I tried neoprogramner, that can't ID either chip and won't even read them.
I might be at the end of the road now, I found a YouTube video saying it won't work
Without taking the chips off the board, I'm not sure I believe that and it's an absolute last resort but I'm feeling beaten at this point.
If only dell could have written a less homicidal update.exe...
:-(
Steve
P.s
I also tried having power to the motherboard, but it made no difference.

Re: Extract BIOS from legacy DELL 1764 flash.exe
Ok, more news, the fight continues..
I've now found both BIOS chips and I'm attempting to write to them.
NB: Neither chip is ID'd, I have to select them from the list, but then both can be raed ok.

Re: Extract BIOS from legacy DELL 1764 flash.exe
Ok thanks.
I had no idea there were 2 bios chips, but how do I know which one the dell .exe corrupted?
Is it possible I need to find the 4mb chip too?
Reading these threads, it looks like there's main,ec and pch bios files... 3?!

Re: Extract BIOS from legacy DELL 1764 flash.exe
ok quick update, I found a post on these forums entitled dell inspiron 1564 bios needed.
Apparently, the 1564 and 1764 are the same.
The files are:
dell 1564 HM55_DAUM3BMB6E0 REV.E REV.A00.bin (1Mb)
1564_DAUM3MB6E0 REV.E REV.A00.bin (4Mb)
I don't know why the original place I found files called them bios.rom and ec.rom but let's ignore that now.
So... I should try writing the 1Mb file above?
(What's the 4Mb file for ?)
Thanks

Re: Extract BIOS from legacy DELL 1764 flash.exe
SMDFlea, many thanks for the reply, I can't tell you how desperate I am to fix this.
Here's my confusion - I thought the bios file (4MB) would go to the BIOS chip
(the 25Q80BVSIG ?) and the ec file (1MB) would go to some other controller chip (unknown to me).
Are you saying I should try writing ec.rom (1Mb) to the 25Q80BVSIG ?
Many many thanks for your advice!

CH341a BIOS is wrong size, where best to ask a question?
Hi All,
I'm wondering where best on the web to ask a BIOS/CH341a question?
I'll ask it here first!:
The BIOS update.exe from Dell bricked my Inspiron 1764 and I've been on a voyage of discovery ever since trying to get it back.
I've managed to take it all to bits and found the Motherboard is DAUM3BMB6E0 (REV E). So I found two BIOS files on the web. BIOS.rom is 4Mb and EC.rom is 1Mb.
I've got the CH341a to connect to the chip (Winbond 25Q80BVSIG 1011).

Re: Extract BIOS from legacy DELL 1764 flash.exe
OK changing my googling from extract from flash exe to bios dump helped...
I found [url]https://www.laboneinside.com/dell-inspiron-1564-bios-bin/[/url]
which has bios for DAUM3BMB6E0 (which I hope is my motherboard).
It states it is revision E. not sure how that relates to the A10 I had installed and the A13 that bricked it. but I don't care if it revives the laptop...
Two things threw me though, two files? ec.rom and bios.rom? Also I expected 8MB but bios.rom is only 4mb.

Many Thanks for that encouraging news, any chance you could point me in the right direction?, I haven't managed to find any.
Much appreciated!

Re: Extract BIOS from legacy DELL 1764 flash.exe
I can't yet post my corrupted BIOS I'm afraid since I have no way to read it yet.
My Service Tag is 56YL8M1.
Currently, I'm planning to purchase a pre programmed replacement BIOS chip from the Netherlands,
read the BIOS code from it and reflash my onboard chip using a*CH341A BIOS USB Programmer.
I've not purchased the CH341A yet since I'm trying to make sure I know what to do when I get it,
there seems to be two chip types(looking at youtube...) and I'm not sure what I've got yet....Leave a comment:

Extract BIOS from legacy DELL 1764 flash.exe
Hi All,
I just bought an old Dell Inspiron 1764 to put Linux on, but
before doing that I thought I'd update the BIOS from windows using
DELL's suggested file FLASHME_v103_Win_1194_4M_1764A13.exe.
([url]https://www.dell.com/support/home/en-uk/product-support/product/inspiron-1764/drivers[/url])
This failed and bricked my laptop and this model doesn't seem to have any usb boot type recovery options.
So now I'm trying to flash it myself using a CH341A BIOS USB Programmer
but can't find any way to get the BIOS image out of... -
Re: New Members - please post your introductions here
Hi All,
I'm from the UK and stumbled over this forum looking for ways to fix my bios bricked dell laptop, fingers crossed there's a way.
