root/cebix/BasiliskII/src/slot_rom.cpp
Revision: 1.6
Committed: 2001-06-27T20:05:23Z (22 years, 10 months ago) by cebix
Branch: MAIN
Changes since 1.5: +25 -29 lines
Log Message:
depth/resolution switching infrastructure should be complete now; slot ROM
contains all supported depths, default mode is stored in XPRAM upon startup,
and added video_switch_to_mode() call (currently unimplemented in all drivers)
