I've downloaded the 2.1.5-R boot floppy and briefly checked the Acer machine that gave me so many problems before with 2.1.0-R ... Hi Stefan! The problem detecting the PCI bus is still there. Now, I'm quite happy that it's not FreeBSD's fault at all, more the rather strange PCI setup in this particular machine. My fix for 2.1.0-R was to compile a custom kernel which reversed the PCI config mode probes (mode 2 before mode 1) and this has proven to work quite successfully. I've also tested the modified kernel on a couple of other machines including IBM and Unisys with no problems either. Compaq Prolinea model 590 machines are still a problem but I couldn't be bothered with those things anyway. Don't have one, don't want one. My question is, would anything be broken or disadvantaged if this change was incorporated into the FreeBSD release, obviously in a later version? Would the "team" be prepared to consider such a change? I'll happily post a diff for pcibus.c here if anyone is interested. My thanks again go to Stefan Esser for the help given in getting 2.1.0-R to run on this machine.
