Any help would be greatly appreciated. Stopping say hd(1,a)/kernel as you do not have both an IDE and a SCSI disk. You are trying to boot from the second IDE disk which is wd(1,a)/kernel. The problem you are having is ``hd'' is magic, it says use the n'th BIOS disk to load, but pass the kernel sd(n - 1) as the root device. Thus it is looking for sd0 on your system for the root file system, and you don't have one... > > ---------- Forwarded message ---------- > Date: Sun, 11 Jun 1995 02:51:49 -0700 (PDT) > From: Howard Lew <hlew@cycle.Stanford.EDU> > To: bugs@freebsd.org > Subject: 2.05 Release > > I just ftped the 2.05 release and tried the install, and the installation > process went well.
