ISA/486 Board Question

Most ISA com/lpt/fdd/ide add on boards for 386/486 have a chip like
W83787F or so. LPT and Com ports have pin-assignable irqs, sometimes IDE
has a choice (14 and 15).
Is there an ISA card that has the IDE irq assignable to any IRQ?
 
U guessed right: I'd like to stick a secondary ide drive (CDROM
obviously) into a 486 that has only one ide (IRQ14)drive, but no plug
for a secondary drive, and no, I cannot use the ide cable as it is a
laptop, but yes, it has the bus connected to a dockstation. And yes I
can stick a scsi card plus drive into the docking station and it will
work in dos, win95 if I find the drivers...but I want to do that with
ide cd's.Is this a doomed idea because the bios wont let me do it?
...the old idea of having 4 ide devices on a single 486 cpu....but with
a twist: the primary ide on the first chip, the sec. on the other....how
do I tell the cpu to look for the sec. ide on the other chipset?
