there are small utilities that allow booting from df1:
they are resident and can survive some resets, they usually have a virus checker, floppy formatter, fastmem off, and similar goodies.
I remember cool one that would turn 'hand holding diskette' into red.
BTW, what would be best and worst A2000 motherboard version for expansions?
(is it safe to assume that newer version are always better?)
