Hi there, I just got hands on an old Dell T1500 workstation. It is not the beefiest monster - but still kicking. And I got it for a bargain :). So, while I was refurbishing it, I wanted to do an BIOS upgrade, like usual. Turned out, Dell only offers a combined "DOS/WINDOWS" Upgrade File. I tried upgrading via an FreeDOS USB Stick, created with Rufus, however - it failed. Ok, lets try Windows: I installed Windows 8.1 x64 - and the tool "worked" - however, even after reboot, nothing had changed. Reset CMOS, Load Default in BIOS, nothing. Darn... Well.. All the Dell support stuff for this machine was around Windows 7-ish versions, so I thought "last chance" 😉 - and yes! It worked:
You need to install Windows 7 x64 and upgrade the Bios 2.0.2 to 2.4.0 via your Windows install. DOS seems to be not working - and Windows 8.1 won't work either. Also for good measure, load the default settings before upgrading and leave all other settings (especially the disabled fancy CPU stuff!) untouched.
Also, you'll see directly if it works: During the Win 7 upgrade, it disabled the USB mouse I was using and it took way longer. On Windows 8.1 - I could move the mouse as I wished. Oh, and one last thing: Administator rights, please ;).
Thank you so much for this. I was getting crazy trying to solve this issue.
It perfectly worked when running the update under Win7
Do not worry, I know that feeling all too well, that is why I documented it here. I am happy to know that it could help you out, take care :)!
Thank you, I just bought an old T1500, I've installed win7 on the second hdd, and the bios update worked fine (1.0.1 -> 2.4.0) 🙂
