[SPARCbook] No luck on X configuration

[troehr at nj-onramp.com]

Michael,

The problems will probably relate to the fact that your SB3 uses a different 
color palette then the 3GX (256 of 512, vs 256 of 262,144) and that the address 
of the video controller may be different. There appears to be no online tech 
manual available for the SB3, only the 3GX. The address can be gleened from 
some interagation of the OBP, and from the dmesg output. Could you forward the 
output from dmesg after a reboot to me? 

Later,

Tom
