epia and vga

Tue Mar 16 03:50:01 CET 2004

Thanks to Ron and Eric's kind words yesterday, and me kicking my brain
into gear, I got Linuxbios and Filo up and running on my epia yesterday.
However, I now have a couple of other issues which I've come to a dead
halt with. I've been trying to add vga support, having extracted the
original vga bios using dd as per the Epia How To. This appears to be
detected correctly during boot and the screen turns on, then flickers
with some garbage on it. If I have agpgart enabled in the kernel I get a
hard kernel hang when the agp chipset is detected - is this normal ?
I've tried this with a 2.4.24 and 2.4.22 kernel with the same result.
Also I never actually get any output on the VGA, just random noise and
colours every couple of seconds. The memory on my Epia is also detected
incorrectly as 64K rather than 128K. Can anyone point me in the right
direction here ? Thanks, 

Matt
