I have a Dell 0XR1GT Motherboard that needs a fresh A05 full bios (w/ME) due to corruption. Bios is MXIC MX25L6406E. I have a ch341a with clip ready to go. I tried biosname.exe /writeromfile etc Just brings up a error window on a working Dell 660 I have. I have 2 spare boards I'm trying to reprogram. Thanks.

Edit: You can't create a firmware with just the extracted dell package, ME is unconfigureed. Correct, this version contains a complete image.

1. thing: Make a 100% correct dump of your old bios.

Run MSK-A05.exe on other system and get error "The system to be updated is not a Dell system".
Don't press OK and go to %temp%\MSK-A05 and save MSK-A05.BIN, then press OK to close the window with error.
Flash it by a hardware programmer.

DeathBringer Thanks ! I'll report back asap with results EDIT: I bought a Pomona 5250 (best clip) and can't get the AsProgrammer to detect the chip. It's still slppery like the cheap clips.

Any ideas/tips on chip connection/detection ? I'm not going to desolder the IC so this thread will probably die at this issue I suppose.
