So i tried installing Relentless on my 486, and the game say my video card don't support VESA or something, i tried using a Cirrus Logic ISA card (GD5320), and selecting Cirrus Logic chipset in the game setup, and it didn't worked.
This board actually use a strange on-board video chipset called "Headland Technology HT216-32-AUPD". I can't find any DOS driver for this or the Cirrus Logic card, and i don't even know if they do support SVGA.
One thing i remember though, i remember i was able to play this game on my 386SX 25Mhz computer at the time (even if the game require 486 25Mhz). So...if i can't do a thing about this ISA card or on-board chipset, what would be a great ISA video card to put in that support SVGA/VESA?
