Bad Bios flash on GA-MA790x-DS4 rev1.0

[n0tiert]

Hi m8´s ,

I have a problem with my Mainboard Gigabyte GA-MA790x-DS4
I tried to update my Bios with latest from Gigabyte: ma79xds4.f5c
Did it from USB Stick (Like several others too), all seem´s OK since there was no Error in Post.....
After Reboot i only get a Black Screen and PC try´s to do some from cd-rom drive....
(Dunno if it search´s for single bios.bin)

My try´s:
Placed old PCI Card inside 1 memory stick hdd & dvd-rom
(matrox mystique works !)
Dos Boot CD
AUTOEXEC.BAT
ibmdos
flashspi.exe bios.bin
even with awardflash.exe /../.. i had no luck
Unplugged PSU & MB Battery for 24h to get checksum failure ... nope not work



The Strange thing is if i place Mainboard Driver CD in it stops checking drive
since i don´t see what he try´s i dunno what i should do
on any other it (my bootdisks) forces to load whatever

Checked the web and found this:

On my Mainboard they placed МХ25L4005 instead of МХ25L8005
so i dunno if that might help in my case to force checksum failure on main bios chip
to gain fallback on 2nd bios chip ... i also have no switch in manual.


My Bios Chips:



might one of you have a idea !

If nothings helps i go for RMA on Saturday i hope the Store change it directly and not sending it to Gigabyte might be a long time to get it back

thx

Hi m8,

The only thing that helped is to RMA it, i went to the Shop and they directly changed it

thx

well the next time you want to do a bios flash, purchase a bios chip for your mobo from this site encoded with the bios you wanted,

http://www.biosmedic.com/

http://www.bios-repair.co.uk/

that way you have a spare chip to flash in case of failure of the other. You can recover a certain way but it can be dangerous without the right tools to recover from a bad bios flash.
also you may want to look at this site for some basics on bios flashing, best bet is to use a floppy disk and not a USB drive or Winflash.

http://www.loggan26.aquiss.com/Custom_Flash.html

i know that site is for DFI boards, but the flashing of bios is all the same just about, just gotta make sure you get the right bios for your board- aka model and revision, to look for revision of the board look at the silk screen.

Yeeeah great idea, but the Bios chip is solder on the MB
(as u might seen on the image) so if i solder arround the guaranty
is lost !
and a dos based flash from usb, or Boot-CD is not that dangerous
than flashing from a dos disk ?! isn´t it ?

the Shop changed it without any questions and no need to pay a single $

but m8 thx anyway for the great try

looks like they cut corners with that board by soldering the chip, you could have the board sent in to that same company i believe to have sockets installed for the bios chips, so you can swap them out for different ones, My system uses a Mod Bios.
