OK. I commented out lpt1 also. Taking a cue from the BIOS,
which gives me 0x278 irq 5 and 0x378 irq 7 as options for on board ||,
I rewrote ppc0 at the latter. As you probably guessed from my kernel,
I was trying to have two || ports, but I took the other i/o card out
so as not to confuse the issue. Still no results with fdisk or mount.
Disklabel hangs also. Output at ^T:

load: 0.07 cmd disklabel 664 [ppbreq] 0.00u 0.00s 0% 148k

Thanks for your help with this.
