Please help me with finding the BIOS image for Gericom Overdose 1540e Notebook.

Thanks in advance.

Is there an issue flashing the SST 39SF040 chip with Uniflash?

Have tried at least 5 known working chips on 2 motherboards (with VIA Unichrome KM400(A) Northbridge + ITE IT8705F Super I/O), but it always resulted in Flash Data Verification Error.

u mean the fans stop turning after rotating for a second?

do u hear any beeps? if yes, try to post here the beep sequence, such as 1 long/2 short, etc. frying ur BIOS chip is a remote possibility, unless u have tinkered with some of its pins while power is ON. try also to reset CMOS by removing the battery for at least 20 minutes, then POWER ON without the...

hmmm, this is a pain in the ass.

some Compaq, HP, and Dell BIOS files are fragmented too.

Definitely a burnt power MOSFET in the ouput circuit of the onboard VRM. It's still possible to POST without this burnt MOSFET ('coz there's still another one in parallel to it), but system will hang due to insufficient processor power. It's not strange that some P4 motherboards don't have the ATX12...

hehe, small world bro...

it appears that the 39SF020A chip is damaged/improperly detected.

try to force flashing with:
A> UNIFLASH -CHIPLIST

copy the 4-character string corresponding to 39SF020A chip...

A> UNIFLASH -FORCE <chipnum>

if the chip is now detected, then go on flashing it.

ur motherboard appears to have no bulging caps, so let's have a look at the capacitors of ur power supply.

Rainbow:

How is it possible to use Uniflash with Intel motherboards whose BIOS file contains small BIOS file fragments instad of the usual single BIOS file?

there's no known fix yet for faulty memory controller, except to replace the chipset (which is equivalent to replacing the motherboard).

u have a system that's behaving erratically...

if u can post a close-up photo of your Motherboard and "Opened Power Supply" for us to have a closer look and so we could advise accordingly.

either of these is true:

1. you are using newer memory chips, that's why your mobo can't detect the full capacity of memory,

2. the memory controller integrated into the northbridge is faulty. i have seen this prob on a number of old AOpen mobo's already, and in other mobo brands as well.

get into BIOS setup and load FAIL-SAFE DEFAULTS to slow down memory timings.

if it doesn't solve your problem, try one memory module at a time to single out if there's a compatibility issue between the memory modules you're using.

but use memtest86+ to test each memory configuration.

That's a board problem. Check for blown or bulging capacitors around the processor area. If any, have them replaced by a qualified motherboard repairman. This hanging up problem plus being unable to restart via RESET button is typical of malfunctioning onboard voltage regulator module (VRM) which su...

No matter what version of Awardflash you use, you won't be able to flash it successfully because of flash ROM protection.

Can you please post the part number of your BIOS chip?

Just peel off any sticker from the chip to expose the part number.
