This is most likely one of the so-called TGA2 boards that DEC
manufactured. It had a low-end Cirrus VGA chipset on it to provide
text mode console support only, ie the Cirrus was NOT intended to run
graphics, and has only a small amount of memory (512K?).
Look on the adapter's endplate for the model number, probably
something like PBXGB-AA (aka Powerstorm 3D30, 8-plane 2MB mem) or
PBXGB-CA (aka Popwerstorm 4D20, 24-plane 16MB mem). You MUST run the
TGA server from XFree86 on these boards.
Running X requires an appropriate "BusID" line the the Device Section
of the XF86Config file; using "lspci" to get the info, eg (something like)
00:0b.0 DISPLAY controller: DEC TGA2
put the following in the XF86Config file:
BusID "PCI:0:11:0" /* note the hex-to-decimal conversion */
Good luck.
