ATA BIOS: ATABIOS.SYS
Overview
ATABIOS.SYS is a DOS block device driver for removable hard disks (such as PC
Card ATA devices), using card and socket services. It identifies and configures
cards with a device ID of 0Dh and a function code of 4 (FIXED_DISK_CARD)
and takes over the INT 13 interface for doing the physical I/O to the device. It is
used with NORATA.SYS.
Usage
ATABIOS.SYS comes with several command line switches. They are indicated
by a preceding slash or dash and are caseĆinsensitive (such as -i and /I both indiĆ
cate the same switch). Some switches are followed by data (text or numeric), in
which the date immediately follows the switch (no space between).
Data Format
"
T is the indicator for a text character.
"
H is the indicator for a hexidecimal digit.
"
D is the indicator for a decimal digit.
EXAMPLE: A switch shown as NTTTTTTTT indicates that the “N” switch is followed by (up to) 8 charac-
ters (such as –nMODEM1). All switches are optional, and if omitted does NOT default to the
switch or the value indicated.
Data Definitions
"
R Retry command after a suspend
"
DH Specify device type (default D)
"
FH Specify function code (default 4)
"
IHHH Specify I/O address (default - first available valid configuration)
Command Line Switches
There are no switches for ATABIOS.SYS.
