1. I seem to be having trouble recompiling a kernel: I think I may 
have messed things up by sup'ing current into my src tree, but I'm 
not sure. I have a custom kernel installed but trying to modify 
the config and recompile yields a spate of errors.

Anyway, what's the best way to get back to a solid 1.5.2 source 
tree? I have syssrc.tgz and am re-applying that. will that do it?

2. I'm curious about the notations SCSI1 and SCSI2 on these 
devices: Mac OS hides a lot of these details. The dribes at sd0 
and sd1 are both internal, so it's not like they have different 
connectors to clue me in. So are most of these devices SCSI2, ie 
twice as fast as the original equipment IBM drive at sd0? Or is 
this referring to something else? Am I losing performance by 
having a SCSI2 device on that internal bus (though a circa 1995 
machine is going to be SCSI1 on both buses, I assume).

3. my clock is losing time, like 10-20 minutes a day. I suppose it 
could be the almost 7 year old battery. shouldn't ntp keep the 
clock in sync, regardless of the battery's condition? I say that 
with the confidence that ntp is running: I need to verify that . .
