Hello Dieter, First off, thanks for taking the time to answer. >I think your VIA card needs to have a "BIOS boot ROM" in order to boot from it. Doesn't look so good there, it's a noname PCI card recovered from an old PC... anyhow the BIOS does not find it no matter what I choose to boot from. >Alternately, if one of the FLOSS BIOSs supports your mainboard, it might >be possible to add support there. That's a good idea, I will definitly check it out. >I have a mainboard with the VT6307 onboard, but I don't recall seeing any mention >of it (or Firewire) in the BIOS. On an unrelated note, are you able to get your >VT6306 into "non-CYCLEMASTER mode"? Indeed the BIOS does not mention Firewire at all, but I thought maybe SCSI could work since SCSI emulation is used for many things. Being not familiar with the CYCLEMASTER mode, I googled around and just tried this: saloon# fwcontrol -u 0 -f 0 send phy_config root_node=0 gap_count=-1 saloon# fwcontrol -u 0 -r After those commands, end of dmesg gives me this: fwohci0: Initiate bus reset fwohci0: fwohci_intr_core: BUS reset fwohci0: fwohci_intr_core: node_id=0x00000000, SelfID Count=2, CYCLEMASTER mode firewire0: 1 nodes, maxhop <= 0 cable IRM irm(0) (me) firewire0: bus manager 0 >You might be able to boot the FreeBSD boot loader [...] >If this doesn't work, I think you'd need most or all of /boot on the >bootable device. Thanks. This is probably the easiest way to go: boot off an USB stick with a minimal FreeBSD on it and mount the FW drive afterwards, hoping it doesn't slow down the system too much. >If your main goal is to get the disks outside the case, you might consider eSATA [...] You are definitely right, but I have a spare FW case I cannot use anymore on my Mac and I don't need very high I/O speeds. So if I can do it without buying new hardware it would be nice... :) Besides, it's a nice little challenge! Cheers Kevin
