Boot Troubleshooting
- If the system hangs right after detecting the hard drives, and your floppy drive light is on, turn off floppy support in the bios.
- If after installation, you get a cannot load kernel error:
- Make sure BIOS is up to date
- Reinstall but do not check the packet mode option during boot block installation process
- Set your HDD mode in BIOS to LBA (don't use "auto", the detected geometry is different if it is set to auto and it fails)
- Set your HDD mode in BIOS to CHS if the above fails
- If the installer fails to start correctly (system reboots), try (try each substep, then rerun the installer each time):
- Make sure BIOS is up to date

dd if=/dev/zero of=/dev/ad0 bs=8k count=16
