Linux is probably the most popular choice for Intel based machines. Before Linux came along, Unix was mostly limited to heavy-duty hardware such as the Sun sparc, HP PA-Risc, etc. Thats why there are so many version of Unix -- each vendor put out a flavor for their particular hardware platform. Linux has helped bring Unix to the masses by popularizing the OS on an Intel platform. Minix (and BSD?) were available on Intel before Linux, but are less popular choices.
Many corporations whose businesses rely on their Unix servers need the power and performance of the more powerful chips from Sun, HP, IBM, etc, so those versions are still dominant in most industries.

PCIC(4) BSD Kernel Interfaces Manual PCIC(4)
NAME
pcic -- PC Card bridge driver
SYNOPSIS
device pcic
device pccard
DESCRIPTION
The pcic driver provides support for older ISA and non-Yenta PCI PC Card bridges. The pcic driver supports most ExCA devices attached to the
ISA bus or PCI devices that do not conform to the Yenta specification.
The following ISA devices, or true clones, are supported in the current code.
Intel i82365SL Step A
Intel i82365SL Step B
Intel i82365SL Step C Intel's original 16-bit PC Card controller.
Intel i82365SL-DF Intel's last version of this device. 3.3V support was added.
VLSI 82C146 An older VLSI part with some issues on some machines.
Cirrus Logic PD-6710
Cirrus Logic PD-6720
Cirrus Logic PD-6722 Cirrus Logic's pcic controller. Compatible with the i82365SL Step C with the addition of a different 3.3V control.
Ricoh RF5C296
Ricoh RF5C396 Ricoh's PC Card bridge chips. These are compatible with the i82365SL Step C, but with yet another different 3.3V con-
trol.
Vadem 365
Vadem 465 Compatible with i82365SL Step C.
Vadem 468
Vadem 469 Like the earlier Vadem models, but with Vadem's own, incompatible, 3.3V control system.
IBM PCIC IBM clone of the original i82365SL part, with its own ID register value. Has no 3.3V ability.
Many other vendors made parts in this arena, but most of them were compatible with one of the above chipsets.
The following PCI pcmcia bridges are supported:
Cirrus Logic PD6729
Cirrus Logic PD6730
O2micro OZ6729
O2micro OZ6730
