video modes tweaking for SiS (and other) chipsets ?

[Czerno]

Hello BIOS folk,

is there a program around for "tweaking" video modes on the integrated SiS chipsets ? I like working in *text* modes with *more* columns (say, 132 c.) -unfortunately, standard video BIOS nowadays doesn't care to setup even one "wide text" mode, maybe the programmers are lazy or they believe everyone boots to windose or other graphical environments ?

In the past there was some "tweakvga" or such utility but of course it is not aware of newer, PCI based, video chipsets (integrated or not)

TIA
