Linux Hardware Compatibility HOWTO: Computers/Motherboards/BIOS 2. Computers/Motherboards/BIOSISA, VLB, EISA, and PCI buses are all supported.PS/2 and Microchannel (MCA) is supported in the standard kernel 2.0.7. There is support for MCA in kernel 2.1.16 and newer, but this code is still a little buggy. For more information you can always look at the Micro Channel Linux Home Page ( http://glycerine.itsmm.uni.edu/mca/)2.1 Specific systemsIBM PS/2 MCA systemsftp://ftp.dcrl.nd.edu/pub/misc/linux/EFA E5TX-AT motherboard has a solvable problem with RedHat Linux 5.0 and possibly other versions of Linux. It spontaneously reboots while probing hardware. To solve, update BIOS to version 1.01. Get the BIOS update at http://www.efacorp.com/download/Motherboard/e5tx101.exe.Many new PCI boards are causing a couple of failure messages during boot time when "Probing PCI Hardware". The procedure presents the folowing message Warning : Unknown PCI device (8086:7100). Please read include/linux/pci.hIt tells you to read the pci.h file. From this file is the following quote PROCEDURE TO REPORT NEW PCI DEVICES We are trying to collect information on new PCI devices, using the standard PCI identification procedure. If some warning is displayed at boot time, please report - /proc/pci - your exact hardware description. Try to find out which device is unknown. It may be you mainboard chipset. PCI-CPU bridge or PCI-ISA bridge. - If you can't find the actual information in your hardware booklet, try to read the references of the chip on the board. - Send all that to [e-mail], and I'll add your device to the list as soon as possible BEFORE you send a mail, please check the latest linux releases to be sure it has not been recently added. Thanks Frederic Potter.Normally spoken you motherboard and the unknown PCI devices will function correctly.2.2 UnsupportedSupermicro P5MMA with BIOS versions 1.36, 1.37 and 1.4.

ExpertColor TX531 V1.0 motherboard with chipset ACER M1531 (Date: 9729, TS6) and ACER M1543 (Date: 9732 TS6) seems not reproducible segmentations faults, kernel oops and kernel hangs under heavy load and tape access. The problem seems to be the PCI-bus, respectively the ACER chipset. I
