(5)FIXED DISK CONFIGURATION / LOW LEVEL FORMAT
This utility configures the fixed disk subsystem, drives C: and
D:
The type of fixed disks may be selected from standard fixed disk
table or defined as user-defined type 46 and 47. The drive parameter
tables are comprised of these entries:
(1) Number of Cylinders
(2) Number of Heads
(3) Starting Precompensation Cylinder
(4) Landing Zone Cylinder
(5) Number of Sectors per Track
Make sure you choose the correct type. Otherwise, the system
will have problem with the fixed disk. If the type of your fixed disk is
not included in the standard table, define it in type 46 and 47. Move the
cursor to the "Type" field and select 46 or 47. Then move the cursor
down to the next field, "Cylinders", and press ENTER. Enter the
number of cylinders, and press ENTER when done. Continue in this
fashion, editing the "Heads", "Precomp", "Landing", and "Sector" fields.
Larger capacity fixed disk drives with higher track density may
have more than 1024 cylinders, but the standard BIOS only supports
upto 1024 tracks. There is a translation mode to surpass the 1024
cylinders limitation. up to 16384 (16K) cylinders can be addressed via
the translation mode. The Translation Mode implementation is designed
to be compatible both with programs which exclusively use the BIOS
interface, and programs which interpret the fixed disk tables and run the
drives directly. If Translate Mode is not selected, only the first 1024
cylinders will be accessible through the BIOS interface.
