Hi all,

ok, first off, we know we should throw NT out the window and start with bsdi 
only 
but ...

I have a question on setting up a dual-boot system with Windows NT 3.51 and 
BSD/OS 2.0.1 My system setup is the following:

DECPC 450DX2 /w 24 meg RAM and a Seagate ST5850A 850 (815) Mb EIDE HD. The 
disk is setup to emulate two disks using jumpers on the disk, thus I 
essentially have 2 hard disks of each 407 Mb, this because my bios can’t 
handle LBA or other esoteric mapping modes. I have NT installed on disk 0 with 
the NTFS file system (which appears as HPFS in the DOS FDISK utility) and now 
I want to install BSD/OS on the ‘second disk’. I have done installations to 
disk wd1 without ‘co-residency’ as I figure that is for installing on one disk 
in separated partitions, both using the wd and the bios bootblocks. After 
running the bootany utility as per the man page I do indeed get a boot 
selection menu and booting NT works like a charm. Not so BSD/OS, if I use the 
wd boot blocks I get a message about no disk label being present, and if I use 
the bios boot blocks it does boot but fails when mounting the root file system 
with a message about incorrect bad block table. I created an empty bad block 
table when installing sin
ce I believe this disk does bad block mapping internally.

Thus, my question in a nutshell, how should I set things up to get this 
working ?

Thank’s for any input !
