Hi all,
I've installed OpenBSD 6.3 on a Pentium III machine alongside existing
installations of Windows 95 and Windows NT 4 by manually setting up a
partition in the fdisk step and using the suggested disklabel
configuration. As recommended in INSTALL.i386, I've emarked the OpenBSD
partition as active.
After booting the PC pauses for a few seconds before displaying "Missing
operating system".
What I've tried:
- "boot hd0a:/bsd" from the installation CD: works
- mark partition 0 active: works, brings up NT's bootloader
- "installboot -v wd0": no change
Any ideas?
Output of "fdisk wd0", "disklabel wd0", and "installboot -nv wd0"
reproduced below.
Thanks,
Sijmen J. Mulder

Using / as root
would install bootstrap on /dev/rwd0c
using first-stage /usr/mdec/biosboot, second-stage /usr/mdec/boot
would copy /usr/mdec/boot to /boot
/boot is 6 blocks x 16384 bytes
fs block shift 2; part offset 16450560; inode block 104, offset 2472
master boot record (MBR) at sector 0
partition 0: type 0x06 offset 63 size 4192902
partition 1: type 0x05 offset 4192965 size 12257595
partition 2: type 0xA6 offset 16450560 size 32901120
/usr/mdec/biosboot will be written at sector 16450560
