Linux v2.1.15 (the lastest development kernel at the moment) includes support for MCA. Earlier versions do not. Here is part of Documentation/mca.txt :
# MCA Device Drivers # ================== # # Currently, there are a number of MCA-specific device drivers. # # 1) PS/2 ESDI # drivers/block/ps2esdi.c # include/linux/ps2esdi.h # Uses major number 36, and should use /dev files /dev/eda, /dev/edb. # Supports two drives, but only one controller. Usually requires the # command-line args ed=cyl,head,sec # # 2) PS/2 SCSI # drivers/scsi/ibmmca.c # drivers/scsi/ibmmca.h # The driver for the IBM SCSI subsystem. Includes both integrated # controllers and adapter cards. May require command-line arg # ibmmcascsi=pun to force detection of an adapter. # # 3) 3c523 # drivers/net/3c523.c # drivers/net/3c523.h # 3Com 3c523 Etherlink/MC ethernet driver. # # 4) SMC Ultra/MCA # drivers/net/smc-mca.c # drivers/net/smc-mca.h # Elite/A (8013EP/A) and Elite10T/A (8013WP/A) ethernet driver # # As well, drivers/char/psaux.c was modified to support IRQ sharing (it's # #ifdef CONFIG_MCA'ed, for your convenience, although PCI users might be # able to use it...) # # The serial drivers were modified to support the extended IO port range # of the typical MCA system (also #ifdef CONFIG_MCA). # # The following devices work with existing drivers: # 1) Token-ring # 2) Future Domain SCSI (MCS-600, MCS-700, not MCS-350) # 3) Adaptec 1640 SCSI (aha1542 driver) # 4) Buslogic SCSI (various)
It looks like your choices are the 3c523, Elite/A, Elite10T/A, and Token Ring cards. Any IBM non-DMA Token Ring card should work. I don't know about stability, since I don't use MCA. There have been some changes in the 2.1.15 network code, though, so make sure you read the newsgroups. See the linux source for more details.
