Accessing the Internal Setup




 The 12F has an internal setup program in it's BIOS that is accessed
using DEBUG at

the controller's I/O address, with an offset of 5.  Thus, if you set
the address to C800, 

you'd type debug , then at the "-" prompt, you'd type g=c800:5

  to access the setup menu.  The latest BIOS as of this writing is #9.00,
and 

this guide is based on that.

When using a tape drive in the "3rd floppy" position, the tape software
should normally 

work fine.  However, if an actual floppy drive is used in that position,
additional software 

will be needed to allow DOS to access the device.  This software, EXFDRV.SYS,
is

available from UltraStor or your UltraStor Dealer.

Each hard drive should be Prep'd with the utility accessed through the
DOS Debug command. 

Normally, the User will initiate a Low Level Format with the AUTOFORMAT
field set to 

BRIEF.  Choosing EXTENDED adds considerable time to the format, which
is fully 

automatic.
