+# BIOS32 Service Directory
+
+GNU Mach is not yet compatible with mmconfig, and PCI access requires the presence of the BIOS32 Service Directory.
+You can check for its presence by running a Linux 32 bits kernel with the kernel parameter "pci=bios" and checking if PCI devices work.

 Some people couldn't get these hardware combinations to work with Hurd.
 
-Note: The Debian GNU/Hurd installer actually runs on Linux, so it (almost) always works. The critical bit is booting after installation.
+The present Debian GNU/Hurd installer itself runs on Hurd, so failure on the installer may mean that the hardware is uncompatible with Hurd.
 
 * ASUS P5A motherboard and AMD K6-2 333MHz CPU - doesn't boot
 * ASUS P2B-LS motherboard with an Intel PII-MMX 400 MHz CPU - this board had a defective onboard NIC (that could not be disable in BIOS) and working 3COM Etherlink III NIC in a PCI bus slot. This combination worked with GNU/Linux. The 3COM NIC is known to work with the Hurd. However, while gnumach/Hurd will boot on this system, it is confused by the defective onboard NIC and unable to use the 3COM NIC. Attempting to start networking generates a continous stream of eth0 and eth1 reset messages on the console that renders the system unusable.

+Currently, GNU Mach requires the presence of the BIOS32 Service Directory for PCI access. 
+The other possible methods are direct access, which is somewhat dangerous and using mmconfig, the preferred default in Linux.
+Direct access is already supported, but only used if BIOS32 is present for safety reasons.
+The relevant Linux code could be adapted and reused.
