That may have to do with how the CD-ROM is burned.  The base spec 
calls for version numbers like that.

I found that an MSDOS boot floppy works fine on a PDQ, but I had to 
change load-base to 500000 (from the 600000 that System Disk set) or 
I got a claim failed part way through loading ofwboot.xcf.  "boot 
fd2:1,OWFBOOT.XCF -a" with the floppy in the left bay.

This was not needed for the boot floppy image from 1.5.2 though.  The 
standard install instructions worked as advertised.

I was never able to set real-base to -1.  OF said that was an invalid 
value and rejected the setenv command.

I have yet to find a good OF device path to access a hard disk (or 
CD-ROM) on this beast.
