I'd strongly suggest setting up a netboot server. You'll need
dhcp/bootp and tftp, but it's way better than trying to deal with floppy
disks and floppy booting.  I've used it succesfully for NetBSD and Linux on
a '140.

I never tried Solaris, because I have no interest in Solaris, but it should
work the same there.
