Trouble booting 4.9 on Compaq DL360

[Matt Reinhart]

Hello,

I recently did a standard ("Developer", no X) install of 4.9-RELEASE
on a Compaq Proliant DL360.  Everything went smoothly.

After the install finished copying files, I tried installing a standard
MBR, but when it didn't work I assumed I made a mistake and tried the
same install again with BootMgr.  After the second errorless installation,
I rebooted and removed the CD from the drive.

Upon reboot, the boot manager and its familiar F1 prompt shows on the
screen.  However, when it tries to continue I receive the following
message: "Error Booting System Partition".  (This is the same error I
received without BootMgr.)  I googled for this message to no avail.

At this point, I rebooted the system from the install cd.  At the boot
prompt, I entered the following:

unload
set currdev=disk2s1a
load /kernel

The system then booted with the configuration I had set during the
install process and is still up-and-running (but cannot be rebooted
without user-intervention).

I have tried `disklabel -B -b /boot/boot0` to restore the MBR, but I
still receive the same message ("Error Booting System Partition")
following the initial bootloader screen.

Does anyone have an idea of what is happening?
