It does. The IDE controler should go in the one marked master.

I think it is.

The rules for VL bus are complex.

The number of VL cards you can have depends on the bus speed, something like

40 MHz, 1 VL card
33 MHz, 2 VL cards
25 MHz, 3 VL cards.

Disk controler cards should go in the master slot, you only have one of those
so only one controler card per machine.

Some manuacturers sy that the cards should be at the CPU end of the bus, some
not, but the whole thing sounds pretty fragile !  PCI is a lot better thought
out and documented !

This Master/Slave slot thing sounds fishy to me !  Check with the OEM, but I
suspect it will amount to slave !
