Latitude LS boot problem - fails POST
This unit worked fine until I recently plugged in the floppy drive (which has also worked fine for years). Now I get the following error in the POST:
[normal stuff deleted]
Video BIOS shadowed
UMB upper limit segment address: EB03
Mouse initialized
ERROR
CR us
ERROR
CR us
ERROR
Fixed Disk 2:
- at which point the unit locks up...
It won't let me go into the BIOS and I tried removing/disconnecting all the various batteries with no success. I also tried to have it boot from the floppy BIOS update disk.
Any ideas?

Try the Dell Diagnostic Floppy Disks.
If you don't have them, they can be downloaded from your Product Support
accessed under Notebooks^ at top left of this page.

# Remove the battery, hard drive, CD/floppy drive, and any PCMCIA card. Remove any external peripheral components such as printers, palmtop devices,
or USB devices. Remove the RAM, this should cause the system to power on and off in a cycle. If not, reinsert the RAM and check the BIOS. Will the system POST?
# Install one memory module, and attempt to boot. Install the second module if the system does boot. If the system does not POST, use the same module in the 2nd slot.
If the system completes POST, replace the motherboard for a bad RAM slot. If the system does not POST, remove the memory module and place the other module in this slot.
If the system completes POST, replace the memory for a bad DIMM. Otherwise, replace motherboard.
