Unfortunately this seems to break USB boot completely for me. When I attempt to boot the USB flash device on the AH-1, the 1 minute delay still exists. The messages "No /boot/loader" and "No /boot/kernel/kernel" are printed, and the image does not boot -- it sits at the "FreeBSD/i386 boot" prompt. It does however see the files at the top of the root filesystem, it just refuses to boot further. The device has less than 1023 cylinders, so the restrictions which would make EDD/packet mode necessary should not apply, and I would have thought that your workaround would work. I am using "USB-HDD" style geometry at the moment (255/63/cc), not "USB-ZIP" (64/32/cc). Would that make a difference? What's interesting is that "camcontrol modepage da0 -m 0x05" returns a different geometry from that reported by the BIOS: %%% Transfer rate: 61440 Number of heads: 16 Sectors per track: 32 Data bytes per sector: 512 Number of cylinders: 3816 Starting cylinder-write precompensation: 0 Starting cylinder-reduced write current: 0 Drive step rate: 0 Drive step pulse width: 0 Head settle delay: 0 Motor on delay: 0 Motor off delay: 0 TRDY: 0 SSN: 0 MO: 0 SPC: 0 Write Compensation: 0 Head load delay: 0 Head unload delay: 0 Pin 34: 0 Pin 2: 0 Pin 4: 0 Pin 1: 0 Medium rotation rate: 0 %%% cheers BMS
