Does anyone have an explenation of why this can happen ?

* check power supply
* compare PCI config space of the "failing" controller to the one
which is "working" (assuming that identical devices are connected
to each), maybe firmware/driver forgets to setup some settings

Promise cards don't support more than two per machine.  If you
can get a third card to work in PIO mode, consider it an added
(but unsupported) bonus.

AFAIR people have been running 4-5 cards just fine

* apic mode is helpful
* current and even more important _identical_ firmware versions on all 
cards, which is quite annoying, since the promise DOS firmware loader 
doesn't like to be executed from a nbi ramdisk, neither on C:\ nor on 
A:\ and I hate booting DOS from floppy.. :-(
