 Here's a little gem for you hardware types. I have just spent a very
exasperating day trying to upgrade a IBM PC-1 to handle a Bournulli Box
and EGA. Both of these require the installation of the ROM BIOS upgrade
for operation. So far nothing unusual.

 After pulling out the old rom, installing the new one, the system
refused to do so much as a POST. The first sign of trouble was the lack
of the cursor on the display. The system sets the screen to black, then
NOTHING.

 I removed the EGA and the Iomega card and still no dice. I got out all
the documentation for the adapter boards and double checked the switch
settings with no luck. It just refuses to boot.

 I replaced the old rom and the system boots normally, although the
Iomega and the EGA don't respond the system goes through the rest of the
POST. Figuring that the new rom might be defective I tried it in a
working system that is configured exactly the same, including the rom
upgrade.  No problems, the rom in question works without a hitch! I then
tried the rom from the working PC in the flakey PC. Nada!

 Both of these systems were purchased at the same time (from IBM) and are 
configured as follows, any suggestions???

IBM PC w/64k system board, 8087 ( new 8088 also )
Seattle 256k Ram Board w/1 serial port (COM 1)
AST MEGA-Plus w/384k installed, 1 serial port, 1 parallel port, clock
IBM EGA with 256k module
IBM Enhanced Graphics Display
Iomega  10+10 (This is the half card w/o boot rom) 2 10 meg drives
 

  I've called the IBM Tech Rep in Baltimore and this is a new one on him
but he's "checking the database" to see if it's happened before.
