1)
Select boot with no startup-sequence in the boot-menu, that should drop you to a cli
2)
Dms's are compressed disk images, they can be written directly to a disk using xdms ( seems to be the latest version ) DMS2HD as the name suggests should write a dms to hd, i've never tried it however.

This might work if dms hasnt changed all too much since 92.

You might also want to get snoopdos and stuff that in your startup-sequence file, that will help figure out what app is crashing
