[comp.sys.ibm.pc.hardware] Monographics card interfering with HD controller?!

wlsmith@valve.heart.rri.uwo.ca (04/01/91)

The situation:
 16 Mhz el cheapo 286 MB (VLSI chipset)
 WD1003 SR2 2:1 RLL hard/floppy controller
 stupid little mono graphics card w/printer port
 
Tried 2 different mono-graphics cards, but they interfere with the
hard drive controller (drive does a half boot, then hangs).  Works
fine with an oem svga card.
Question: Why should cheap stupid little mono graphics cards interfere
with the hard drive controller card?  Memory conflicts? (shouldn't, the
controller can't occupy the same space as the display).  Any ideas?
