I'm having some problems adding a (Mitsubishi) floppy drive to an apollo dn3000 running sr10.2 . I wondered if there is any jumper that needs to be removed on this kind of floppy drive. The floppy drive was installed as it came out of the box, following the instructions in the "Installing Hardware Options in Your Domain series 3000". It cannot invol or write data to the floppy diskette. I know the problem is not the diskette for I've used the same diskette on another floppy drive (from NEC). roque% ts /etc/invol Ver Name Time Stamp File Name -------------------------------------------------------------- c 1 os_invol_start 1990/06/22 1:21:18 EDT (Fri) /etc/invol roque% /etc/invol invol (initialize_volume), revision 10.3, June 22, 1990 1:20:24 am ... ...
