I yesterday tried the HWDIRECT.173 kernel with serial console, no
success though!
This is the result from Mac ROM. One strange thing is; that it says that
the internal disk is an IDE? As I said erlier, I have made changes to
the motherboad, to make it run at 33 MHz instead of 25 MHz. May this
change cause any troubles? MacOS itself can't no longer recognise what
kind of Macintosh model i've got. I'm planning to setup a cross-compiler
on my Sun SparcStation 5 at work. This to make the LC/Performa 475 run
NetBSD. Help is welcommed!
