The serial port is working correctly (verified with Windows and > later with NetBSD). CD-ROM booting uses a separate bootstrap (src/sys/boot/i386/cdboot/cdboot.s). It does depend on a non-ancient BIOS. NT 4.0 uses the same CD booting method that newer FreeBSD snaps use FWIW. To debug this you would need to hack on cdboot.s to find out when and where it dies. -- John Baldwin
