SUBJECT:
EQUITY I/II HARD DISK INITIALIZATION
This is a basic guide for the installation and initialization of
hard drives
for the
Equity I and II, Those of you that have the
SPHDD.BAT may continue to use it;
there are also a number of
excellent third-party utilities, such as SpeedStor, that may be
used.
However,
this method can used with just ‘the systems
software as provided with each machine.
1.
Before
physically
installing
the drive,
either
copy the
information from the defect list on
the top
of the
drive or
make sure
that you have the copy that was included with the
drive. What you'll be needing is the cylinder/head information
- you don't need the byte location.
2.
Verify that the terminating resistor pack is installed and
that the drive select jumper or
switch is correctly set. The
drive
should be selected as
the lowest number - i.e., DS0
assuming a range of DS0-DS3.
3. Some drive manufacturers do the physical or "low-level"
format at the factory.
DON'T ASSUME THIS! One indication is
this: start the HDFMTALL program. If the cylinder count-down
goes quickly (approx. 1
sec.
per
cylinder),
then the physical
format is
very likely sound. If
it takes
longer than this,
other measures are called for. Re-boot the system and proceed
to step 4.
4.
Invoke the DEBUG program. At the dash (-) prompt, enter:
g=c800:5 and press ENTER. At this point, DEBUG executes (Goes
to) the instructions at hex address c800, offset 0005. This is
the ROM BIOS on the HD controller card. Stored at this address
is the physical formatting routine provided by the controller
manufacturer: You may encounter two types:
Western Digital or
National Computer
Labs (NCL). The Western Digital is the
simpler of the two. It presents you with information about how
the drive number and
interleave factor
are stored in the AX
register and prompts "Press y to begin formatting drive C with
interleave 03". Press any key other than "y" and it aborts. If
you enter "y", it IMMEDIATELY proceeds with the
format. DON'T
PRESS "Y"
UNLESS YOU REALLY MEAN IT! It will then inform you
when the format is complete and return you to the A prompt.
