It depends on what you mean by "second ide card." Just plugging in a second,
vanilla ide card (or "multi-I/O" card) won't work. You need a card that uses
INT 15 and, in most instances, that provides the BIOS extensions needed to
support 4 devices (as well as ATA CD-ROMs and large-geometry drives ... that
is, EIDE or "extended IDE").

Fry's sells several cards of this type. I've used a couple of different ones
and they all seem to be functional equivalents. (I've actually used them to
add ATA CD-ROMs to Linux systems but not to add hard drives ... but I'd be
surprised if they don't work properly for both uses.) Price is $25-30. One
example is the "Promise EIDEMAX" card (Fry's part number 2316379).
