I've been booting for the past week off of the SBC #12 with no problems. 
I installed SBC #28 (the newest I could find). While booting, the 
computer hangs at this line:

sbc0 at obio0: options=1<PDMA>

After that line is displayed, the light on my EZ drive stays red as if it 
was accessing, but you can't hear it accessing. I sat there for about 15 
minutes, with no change in status...

Configuration information:

Performa 600 (no FPU)
12MB RAM
Booting off of: SyQuest EZ 135
  15MB Mac OS partition
  20MB swap
  100MB root&usr
Internal 160MB drive (manufacturer: IBM), all partitioned for Mac OS
comp121, base121, and etc121
I boot with no extensions on, and monitor set to black and white

I hope I left nothing out on that config stuff there. I re-installed #12, 
and it works fine (except for a string of parity errors on my internal 
drive, which it's been doing...that's why I wanna upgrade, to get rid of 
those)

I'm going to go get #27 and see if that's any different. I may work down 
until I find a usable kernel...

Any help would be much appreciated...thanks!
