VESA driver failure on Toshiba 4100/Trident Cyber9525

I’ve installed RTP onto my Toshiba 4100XDVD directly from the (initial)
CD, and so far, so good - except for the video. RTP selected a plain
VGA driver, which was O.K. as a “safe” choice, but I’m not having a lot
of luck getting it going with the VESA driver. The Trident Cyber9525
chip claims full PC98 compliance, which includes VESA 3.0 compliance,
but when I modify the command line for the graphics driver to read:

io-graphics -g800x600x8 -dldevg-vesabios.so
-P/usr/photon/palette/vga4.pal

the system hangs on the re-boot with the message “Mode not found in
table”. Well, if 256-colour 800x600 isn’t in the VESA table, what is?
For that matter, once I get the VESA diver going, I should be able to
switch to one of the 1024x768 modes, yes?

Someone please help - 640x480 is getting real old real fast!

I have another Trident-based laptop and vesa driver does not work
either. The SVGA driver works though…

Sorry - WHAT “SVGA driver” are you talking about?? And what is the max
resolution supported by that driver?

The devg-svga.so.
It is generic SVGA driver, supports up to 1024x768x16 (for me anyway).
Unlike VESA driver it works in ‘bank switched mode’ which is why it
works with some cards that VESA driver does not like. It is part of
patch A, released Jan 18.

Thanks Igor! I hadn’t downloaded Patch A yet, so I wasn’t aware of it. I’ll go
get it now and try it out.

Quick update: Patch A downloaded and installed without a hitch, and correctly
installed the SVGA driver at 1024 x 768 in 256 colours. I then bumped it up to
1280 x 1024 in 256 for use with my dektop monitor. Beautiful! Now all I have to
do is get it to see my 3Com 574BT PCMCIA Ethernet card - but I’m working on that.

Thanks again, Igor!
