If it would be just a die shrink without changing any internal registers and logic then there's no reason why G450 not work (after changing DID) with old drivers. But as there 2nd RAMDAC was added it would be reason that some internal logic was changed and that could break the compatability with …

Thanks for info, it's really noticable speed up. I will test on my GTX970, I expect it's affected the same as 980.

Good idea, unfortunatelly I don't have any from this range, only 230, 270, 670, 970. Couldn't you extract from full image file for card vbios update?

I also got this VGA from a friend few days ago who saved it from a trash, already with removed bracket and heatsink. I fixed bent pins and did a quick test - it seems to be alive, VMT passed. I also updated VBIOS to the latest version 2.1 but it didn't add any new VESA modes. My LCD has native …

Now I was wondering how easy it is to get the EXTERNAL midi device working on the Sb Live 5.1! I'd be happy too if I could connect my dreamblaster MIDI to my SB Audigy, via gameport header or other herader. But it would probably need some extra programming to setup the MPU UART. I don't know if it …

No, it cannot be moved to different partition size without changing specific values in bootsector image, you would have to boot DOS from other media, run sys command to create new bootsector on your new partition and then save it to file. Then repair NT bootsector from install media or via bootprep …

The only thing needed for NTOS dual booting is to save existing bootrecord from partition (DOS bootrecord, not MBR) to a file (there are various tools to do this), e.g. bootsect.w98 and then, after installing WinNT/2k/XP add one line to boot.ini: C:\bootsect.w98="Your old DOS name" if it was not …

What you mean by "force new Vmware PCI driver in device manager instead of original Vmware one"? Replacing a driver from your old installation? In my case it just installed driver from SoftGPU package instead std. VGA driver.
