VESA requires realmode.

VESA also requires *nomp=1 in your plan9.ini.  i have
seen the pointer hosed, though.  i haven't gone to the
trouble of understanding vesa well enough to know why
this is.

you might also try 1280x1024x16.  that mode works pretty
well for me when other modes fail.

9fans,

> VESA requires realmode.

Thank you Erik, it was an oversight from my part. I was able to start rio
in 1024x768x8 and 1280x1024x8 using the VESA driver, however, the keyboard
was not working, and the pointer had no cursor.

Please note, that, while the pointer had no cursor, the mouse was working
fine, and I was able to open windows, although I couldn't type anything in
them.

This is what I bind (cpurc) before starting rio:

  for (i in m i S t U P)
	bind -a '#'^$i /dev >/dev/null >[2=1]

Please note that I'm using a PS/2 mouse and keyboard, and I am not
starting the usb daemon. Finally, the keyboard works fine at the Plan9
boot prompt. Should this matter, aux/vga doesn't use the '-c' option.


Any thoughts?

9fans,

I'm using a VIA SN18000G booting off a fileserver, everything seems
to be working relatively well, however it seems that the video card is not
recognized. My 'pci -bv' and 'vga -lvp' are as follows:

Is there any way to force this card to use the VESA driver? Please note
that I'm booting using "*norealmode=" in my plan9.ini.
