I would like to add an old unused IBM XT WD1002S-WX2 with a 85MB drive to my 386 AT. The 386 has in it an IDE interface (16bit) with 1 ST1144A (120MB). I've checked to make sure a) Theirs enough wait states for accessing OLD 8bit boards b) The I/O ports 320H-323H are unused in the AT c) the BIOS EPROM is addresses from C000:8000 upto C000:BFFF and that area is unused in the AT (THE VGA board EPROM is C000:0000 upto C000:7FFF So, will I blow anything up adding this to the system (power supply has also been checked)? Will it work? Which drive will be #0 and which will be #1? ******Will their be any conflic because both use IRQ5? Will I have to switch the MFM to IRQ2 (its switchable)? respond via email to grossman@bbn.com
