The only thing you need the 512 byte support for is reading 
EFS-formatted disks.  In other words, installing software.

Take my word for it: you never, ever, ever want to install IRIX software 
from CD-ROM.  It is a horrifying orgy of disk-swapping.

If you happen across an EFS CD-ROM, stick it into a Linux PC, take an 
image of it, then mount the EFS image with -o loopback.  Then copy the 
data to an install server.
