I guess the ps2 ports are knackered, I downloaded the Bios Update v05 and imaged it onto a few different floppies but everytime i boot from any of the disks it always stops at "Loading Rom Image" the green light on the floppy drive is lit yet theres no activity from the disk
Have also swapped memory to see if that was causing it with no luck Have also reset the Bios and changed the CMOS battery, none of which have made any difference.
Re: Dimension 2400 Keyboard Controller Failure and other problems
The chain of evidence suggests the chipset, permanent part of motherboard, is knackered. USB drivers support Windows-specific keyboard features, but the system is supposed to respond to USB keypresses without any software loaded.
Thorough procedure, I'd say, resetting BIOS, changing battery, swapping memory, trying different configurations. If you could swap PS2 keyboards with one that definitely works on another machine, that leaves only chipset/motherboard.
