Flashing Dell BIOS from UBCD v5
Posted: Thu Apr 09, 2015 10:30 am
Hello there .o/
I've tried making a tutorial for someone on another forum about how to make a custom version of UBCD 5.3.3 so he could update his Dell Dimension 9100's BIOS before upgrading to a better CPU.
Basically I told him how to make a custom CD using the built-in ubcd2iso, then to boot on "UBCD FreeDOS R1.51 (Based on NwDsk V3.40)" and run the update program from Dell (the actual thread in french over there). Unfortunately, he reported that the update failed with the following message :
However, flashing the BIOS from a Dell Optiplex 360 does work with UBCD 4.1.1 when booting with "FreeDOS Boot Disk V3.40" : I had done that several times before, and tried again, successfully, this evening on one of the computers that failed to update using UBCD 5.
Hence my questions below :
- Did anyone else try flashing Dell BIOSes with UBCD 5?
- Did it work for you, or did you have any issue? Which method exactly did you use? On which computer models?
- And last but not least: any idea why my method didn't work with UBCD 5 while doing pretty much the same with UBCD 4 works just fine? ^^'

So, I tried the method I had given him on two Dell Optiplex 360, once choosing the default option "Boot UMBPCI (silent)", and another time choosing "Boot no UMB (defensive)", disabling everything except CDROM support and french keyboard : it failed for me too, with the very same error message. I did check that the BIOS update program had been burnt correctly.update failed!
the flash image failed one or more consistency checks.
