I have a Emulex MD21 controller driving a Micropolis 1325 disk (130 MB) ex SUN
shoe box. The software driver is Silver Lining 5.17, on a Mac SE 6.0.4. This
config has been working fine for 18 months. Now, this same drive will not 
work properly with a Mac Plus and it has something to do with the way the 
SCSI chip polls the device and requires booting from a floppy before the 
drive will be recognised.

I hope this has been some help, if I can be of some more help mail me.

PS. Mike I tried to mail you direct but I got a mail message User Unknown, our
software people think its a problem on your end. You may wish to check it out.

Regards.
