Hello,
I know that this is probably a long shot, but I figured if anyone could find this BIOS, it would be you guys.
I am working on an (old) eMachines T6520 desktop PC that might have a corrupt BIOS.
Model:
eMachines T6520
Motherboard markings:
MS-7145B0505068731
RS480M
7145 v2.1 RS480-A21+SB400-A23
Symptoms:
The computer does power on, CPU fan spins, but does not POST. No display.
Troubleshooting steps so far:
Replaced the CMOS battery (which was in need of replacing)
Re-seating and then replacing the RAM, but that had no effect.
Installing a different compatible CPU, but that also had no effect.
Disconnecting all other devices except for motherboard, CPU, RAM, and PSU - no effect.
This computer is from around 2004-2005ish. The BIOS chip is a Winbond W39V040AP PLCC32 and the motherboard is a customized OEM-version of the MSI RS480M. I have already taken a BIOS dump of the existing BIOS, but I soon found out that finding a replacement BIOS isn't as straight forward as usual.
The first problem, as I'm sure we all know, is that eMachines is no longer a company. It was sold to Gateway in about 2006 and again sold to Acer around 2012. Acer no longer provides driver updates for the old eMachine models. I used WayBackMachine to find the original eMachine driver download page for this model and it turns out that eMachines never provided BIOS updates to begin with, only drivers.
I have searched everywhere to try and find the BIOS for this model and have had no luck. I did find one well known pay-wall website that offers bios files, schematics, etc that claims to have this BIOS file, but I have always been suspicious of these types of websites and not sure if it's a scam or not, despite it being well known and often comes up in Google search results. That is the only place I have found that claims to have it.
As far as I am aware, I cannot flash the MSI RS480M to this computer because it has been customized for the OEM (eMachines) unless someone knows something I don't about doing that. I have attached the BIOS dump that I have taken.
Hopefully someone can help! Thank you!
