hmmm. i think there's a chance this might work if you do this:
...
- put the data beyond 1440k onto a 3rd floppy2 (eg, something
like "dd bs=1440k skip=1".)
The dd seems good but then booting gives "Data Access Exception".
"http://www3.fr.netbsd.org/ports/sparc/faq.html#floppy-memory-
boundary"
This Sparc 2 has 16 x 4 MiB SIMMs. The Web page says the problem
was fixed; it must have crept back. Pity. I'll try the CD or network
install next.
My diskette procedure follows in case anyone is interested.
