System: NetBSD emmas.up-vision.de 1.4ZA NetBSD 1.4ZA (EMMAS) #0: Tue Jun 13 11:07:00 CEST 2000 martin@wilhelminas:/usr/src/sys-i4b/arch/i386/compile/EMMAS i386
(the system is slightly older, but biosboot was build from sources updated
via cvs today.)

>Description:

When installing current bootblocks, my system won't boot from harddisk.
The biosboot (Revision 2.7)  loads, saying it will start to boot
fd0a:netbsd in 5 seconds (note the fd0a!). When stopped and told to use
hd0a it hangs.

This is very similar to a bug fixed a few weeks ago when a pointer to another
copy of the partition table was examined.

An older version of biosboot (Revision 2.6, build on March 15 by tron, from
a -current snapshot some time ago) works just fine.

This disk is brand new and only ever has seen NetBSD. I installed it by
plugging it into another NetBSD machine and using disklabel. No other OS or
tool was involved.

Here is the dmesg output relevant to disks:

pciide0 at pci0 dev 7 function 1: Intel 82371AB IDE controller (PIIX4) (rev. 0x01)

And here the disklabel of wd0:

The output of fdisk is:
