There are only a bunch of bytes different from the MSI to the XFX.
Where did you get the .rom for the "slimline" HP card?
Can you share it?
(possibly a "whole section" of the .rom will be missing or however i will be possible to understand which are the different bytes related to the fan speed.
Also, the Gainward.G210.512.090915.rom and the Galaxy.G210.512.090829.rom are VERY similar to both the XFX and MSI, have you tested them?
Yupp, I got the BIOS from a physcial card of a HP Slimline from my real world friend by nvflash, here it is:
backup (70.18.09.00.06, Work one).rar 39.91KB
And these are the BIOSes which I tried:
Nearly all of them can make the card works, but many of them will halt / scrap the screen after loading the driver.
Yupp, Both tried, Gainward G210 one could work, but missing energy saving function on different loading of the card (If I remember not wrong).
Note: 1) In Nibitor, All downloaded BIOSes from Techpowerup can display the RAM/Clock speed correctly, but the BIOS from my friend's HP G210 can't.
2) Also in Nibitor, all BIOSes (included the one I attached) show the fan speed will change at 30%, but no luck whatever you change it.
3) According to other posts in the net, G210 VGA board shouldn't come with a fan pwn controller, so there must have tricks that Pegarton overcome it. As BFG G210 / EVGA G220 also have fan issue and maker had provided updated BIOS for it long time ago for fixing. How sad that I even can't get a BFG G210 BIOS for a tried since it gone.... (No luck in webarchive.org)
4) The device ID of HP Pegatron G210 card is 10DE:0A60, but all other G210 BIOSes in TechPowerup is 10DE:0A65. Seems that Pegatron G210 card use older GT218 core revision (OEM), but retailing card use newer revision of the chip.
5) Nvidia BIOS has checksum, just change some byte in it will make the BIOS corrupt and can't light on the card.
