I have however found that waht is happening is that on boot it goes into Floppy.
I have gone into the boot section F8 and changed it to boot from HD C: then on boot it boots OK.
The problem is that on next boot it repeats the same ARC FIRMWARE problem so I do a repeat in the boot section F8.
For whatever reason when I change it to boot to HD C: it does not remain locked in to that setting but keeps reverting back to boot from floppy.
All help appreciated.
