 To my best knowledge I do have a 5380 SCSI controller in the machine, 
based on my research.  I've attached the dumps that the Penguin booter 
"Hardware" menu gives me telling what hardware and address ranges it 
detects, that too tells me that I have a 5380 chip (SCSI_5380 : Yes).  Not 
sure on the address range, though.  It looks like 0x50f08000 falls in the 
range of SCCRd and SCCWr (0x50F04000), if the data is correct.

 If I do have the 5380 chip, it looks like one of the 2.4 kernels may be 
worth looking at.  Does the kernel file need to be named "linux" for the 
Penguin booter to recognize it?
 Thanks.
