In DOS time there been third-party utility for video BIOS loading without flash, just direct from command line or as device driver from config.sys
Now i need it and completely forgot it name(((
Need help? Begin with photo and model of your hardware 😉
Hi there! Yes, there two kinds, I think.
a) VESA VBE TSRs (they install VESA BIOS extension in RAM)
b) Utilities that copied VGA BIOS into RAM
Then, there were shadow ram utilities that moved ROM code into the 640-1MB region.
I forgot the name of b), though. My OAK VGA has it on diskette, though.

SVBL (Shadow Video BIOS Loader), but it only works with Intel 430 and SiS 496/497 chipsets.

Tnx! I have a Intel 430NX, 430TH and 430HX motherboards… give it a try!)

You're welcome! 😀

Not tried yet.
Is it dedicated to nVidia cards ?
Anything more general, like S3 cards or Via chipsets ?
What is the benefit of copying VGA BIOS to RAM?
In some cases: new features, more/better fonts, etc.
For shadowing alone, emm386 has the ROM= syntax to shadow any rom.
Doing so enables much better memory access, especially with isa video cards, which improves how rom supplied vesa routines run.

It helped me fixing glitches. ^^

Yeah, I would like to try a fix.
I know I can program the EEProm, but patching on file may be faster.
