PC Based Injection computer- Caution!

[Thor Johnson]

Actually, I remembered something (never happened before... strange)-
  on anything later than an XT, the bios is REQUIRED if you want to use 
the cardslots (because the AT bus still runs at 8 MHZ, and the Chipset 
handles the slots/????) mapping.  We tried a homebrew setup on a 12 MHZ 
286, and got nowhere... moved it to a 8088, & it worked.

Note however, the BIOS is designed to look for additonal ROMs to execute 
(like on the VGA card).  I don't know which adresses, but if you put your 
program there, the bios will have setup the bus, and then pass control to 
you.  Whether or not you give it back is your decision ;)
