I have just setup linux on a 486-33 vlb + et4000 vesa card (TMC Research
Corp, Taiwan - PAT48PR & SG400AV are the part numbers). The vga card
documentation is underwhelming to say the least, but the setup programs
do claim that there is a 32k dac is installed. X (linux v1.1) works fine,
but that is contrary to my understanding that it should not like the
newer dac.
A unscientific performance comparison between this machine 486-33/8MB linux
0.99.4, and a gamma release bsdi running on a EISA 486-50, 16MB, ISA et4000,
didn't show much between them (the test was messing around with ico and
xv).
The clocks are provided by a variable oscillator on the vga card, but there
X does not have have any problems finding them (I have used frequencies
from 25 to 90MHz in the last couple of days - there is only one can on
the board).
