I found this page that suggests it was used in a PC made by Haier. Haier has a driver download page (in Chinese) for its various PC models, but I couldn't figure out which one(s) contain the P4P800-M.

OEM manufacturers ask companies to prepare special versions of their well known MoBo's for their crappy PC's. Same thing goes with Gigabyte, numerous non-googable model names I've encountered.

I've seen also ECS, MSI and Biostar mobos in OEM PCs as well, but this PC with the P4P800-M looks more like a custom build, it has no brand at all and seems to use regular parts, i know the videocard from that PC is a Gainward Geforce FX 5600 SE and the optical drivers are just aftermarket LG and MSI drives, the PSU is not OEM ehtier, although it seems to be posterior (B-Move branded with 24 pin ATX), probably because the original PSU died or something

After some time, i took pics of my board and tested it, sadly, this board is probably faulty, the onboard audio doesn't work and the BIOS is doesn't save it's settings (once i unplug the computer from the wall, the BIOS resets istelf even with a good battery). CLRTC1 jumper is set to normal

I remember Fujitsu Siemens using custom Gigabyteboards and I also couldn't find my exact model number of my KT600 sA board. Iirc it even had the P4 power plug 🤣
I kinda liked that board though, but FS seemed to have used pretty solid boards (for an OEM) and their XP media was basically just a standard XP install disk which would auto-activate on many different FS boards.

maybe the new battery needs to sit tighter, try pulling out the metal prongs in the battery holder so that the + and - sit tighter. I had that problem with one of my boards.

I tried. doesn't work, BIOS still forgets it's settings and the same CMOS Checksum and date/time failure

I remember having a custom Gigabyte mobo from a Fujitsu PC, model is GA-8STXC and is based on the SiS 645DX, it has the universal AGP slot
