I more-or-less solved my problem by switching motherboards. I tried the 
1542CF on another '486 MB and a '386 I had access to. Both work fine,
using same termination, cables, disks and card. So, my assumption is
that the original '486 I tried, may have some BIOS problems or whatever.
It still could be an interrupt problem, but somehow I doubt it. It's
a VLB motherboard (no PCI), and I checked (and double-checked) the
interrupt settings of all my cards. I also stripped the original
box from most other cards (like ISDN/SOUND/ETHER), and retried but
it didn't make a difference...

Well, I've swapped motherboards, which for a 386/486 is a low-cost solution
nowadays, so basically my problem is `solved'. Still curious about why the
original MB is problematic, but alas...

Thanks for all your tips,

Feico.
