A quick search of the Gateway site turned up this BIOS update:

which brings you up to P13, if the motherboard P/N is one of those
listed on the webpage.

Thanks, I upgraded to P13 which at least is a bit more current.
Apparently entering the first part of the BIOS ID into the download
search at gateway can pick up these updates. Unfortunately, no BIOS
RAID feature in that release.

I discovered my D875PBZ resetting problem had to do with using
dual-channel memory. If I have channel A and B populated and BIOS P03,
which was what comes with every board I've received thus far, the
system boots and works until iflash upgrades it to P33, then the system
hangs and no efforts to revive it will work... until you remove memory
from channel B. Then it boots and shows CMOS menus, etc., just fine.

So I checked the CPU part of my documentation, and found it indicates
using Pentium 4 2.4C, 2.8C, or 3.0 CPUs in it. I am using a Pentium 4
2.4A. Apparently there's some issue with dual-channel memory timing and
the A/B series of CPUs that make it incompatible. (I've also not been
able to initialize the driver for on-board ethernet, so I disabled it
and put in a PCI interface.)

I understand this motherboard also dislikes Prescott technology CPUs
(Intel's tiniest transistor size for Pentium 4 478 package). I have
written Intel asking if a Pentium 4 3.0C will work (Northwood), or
whether I have to scare up one of these older CPUs for this
motherboard. We're up to rev E with Prescott, and therefore some of the
older CPUs are a bit harder to find.
