Indeed, things didn't work well when I dropped the trailing zero !
01:00.0 VGA compatible controller: S3 Inc. Savage 4 (rev 02) (prog-if 00 [VGA])
Subsystem: Number 9 Computer Company SR9 8Mb SDRAM
Flags: bus master, 66Mhz, medium devsel, latency 248
Memory at feb80000 (32-bit, non-prefetchable)
Memory at f0000000 (32-bit, prefetchable)
Capabilities: [dc] Power Management version 1
Capabilities: [80] AGP version 2.0
After changing the base, and upping the size back to 8M, things at least
are still working ;-} So XFree86 indeed was wrong !
Now I just need to get sound working... ESS Technology ES1988 Allegro-1
seems to be very new
Thanks much !
