Hi,

Ok, who has that BIG pointy hat?  After spending about 4 more of testing
I found the problem....  The PCI chipset was remapping IRQ 11 for INT C.
Well since the 1542CF and my drop in IDE were both on here, it gave me fits.
Once I went though and reset it to use 9, 10, 14 and 15 it runs fine...

Gary
