I'm having a problem with a new install. Upon reboot the system hangs on "Bad 
PBR Sig". I can boot in single user mode via the install disk and mount the 
freshly installed software (I'm even asked if I'd like to mount the system a@/a 
during boot). Everything appears to be just fine.

What I have tried thus far...

- Boot into single user mode and issue `dd bs=512 count=16 if=/dev/null 
of=/dev/rdsk/c0d0` in an attempt to wipe the partition table. I then 
reinstalled and was welcomed w/"Bad PBR Sig"

- Boot into single user mode and issue `/a/sbin/installgrub -m 
/a/boot/grub/stage1 /a/boot/grub/stage2 /dev/rdsk/c1d0s0` and reboot. I'm then 
greeted with "GRUB", and the system hangs (I am unable to do/type anything at 
this point, hard reboot required).

- Boot into single user mode and wipe the drive clean via format, relabel, and 
reinstall (emulate a brand new drive?). Again, "Bad PBR Sig".

- Boot into single user mode and issue `dd if=/dev/zero of=/dev/rdsk/c0d0` and 
reinstall. Again, "Bad PBR Sig".

- A combination of the above. The best I've managed thus far is "GRUB".

The hardware that I've been trying this in consists of a dual P3 700MhZ w/1G 
RAM, 2 PATA 80GB drives (c0d0 and c0d1) and a DVD ROM (secondary master). Both 
of hard drives are ones that I had left over from an old Linux software RAID 
that were working just fine when removed. Both drives are configured in LBA 
mode in the system BIOS and I'm using c0d0 as the boot disk for both the BIOS 
and Solaris installer (AFAIK)

I also had this issue in a newer system (P4 3.0GhZ w/4GB RAM) using a single 
20GB PATA drive that previously had Linux installed on it. I eventually got 
that working but I do not recall exactly what worked of the several things that 
I tried.

Per Google, it appears that this isn't a very common issue and, thus far, no 
"silver bullet" to fix the issue has been identified. Any ideas?
