10.IDE Driver installation
This chapter provides information on how to install IDE hard disk drivers that come in the
floppy diskette with your PI-6582V card. Please note that there must be relevant software
installed in your system before you could proceed to install the IDE hard disk drivers.
10.1 Installing the drivers for DOS and Window 3.1
!"
NOTES ABOUT INSTALL PROCEDURE
Please type
INSTALL
from install diskette to install driver for ALi Master IDE controller.
!"
NOTES ABOUT SETUP.EXE
After successful installation, you can run SETUP.EXE (from where you just install it) to
re-configure driver if something need to be changed. This utility can configure ALi IDE
driver for DOS and Windows.
Please type
SETUP to configure driver option.

ALIHDD.SYS Command Line Definition
This device driver is used for ALi local bus IDE chip.The hard disk drive performance
will be tuned in the optimal condition by this driver. SETUP will add this driver in
CONFIG.SYS in the following way
DEVICE=[DRIVE:][\DIRECTORY]\ALIHDD.SYS [/Sxx] [/IOW:xxxx] [/LBA:xxxx][/Ixx] [/BKM:xxxx]
Please use SETUP.EXE to re-configure these parameters rather than modify
CONFIG.SYS directly.
If some hardware configuration are changed, SETUP.EXE must be run and "AUTO
DETECT" function must executed to update the driver's parameters.
1. /Sxx Specify the Local Bus Speed.
Please specify your PCI local bus speed of system. The valid value must be
20MHz - 50 MHz. Assign this parameter for driver to adjust the best performance
for your harddisk drives. The default will be 50MHz without assignment.
For example: use /S33 when your PCI local bus speed is 33Mhz
2. /PIO:xxxx Specify the PIO mode for your hard disk drive.
Add this parameter if you want to assign fixed PIO mode to some hard disk drive.
Default will be AUTO if no /PIO:xxxx assigned. Here 'AUTO' means ALIHDD.SYS

will identify your hard disk and select PIO mode timing according to hard disk drive
supported PIO mode.
3. /PIO:abcd
d: Secondary channel slave drive use PIO Mode x
c: Secondary channel master drive use PIO Mode x
b: Primary channel slave drive use PIO Mode x
a: Primary channel master drive use PIO Mode x
For example: /PIO:12AA
will use PIO mode 1 for primary master drive, PIO mode 2 for primary
slave drive, AUTO detect PIO mode for secondary master and
slave drives.
If some harddisk fails to be tuned by this device driver (not stable), try to add this
parameter. This will happen when the harddisk drive does not support PIO mode 3 or
above.
For example, we will AUTO tune Quantum ProDrive LPS 240A hard disk to mode 2
timing because this drive reports itself supports PIO mode 2. But we find it is unstable
when using mode 2 timing. In this case, you can add /PIO:xxxx to adjust the timing to
mode 1 for this Quantum drive.
4. /Ixx Specify the secondary IDE control IRQ.
When one or two harddisk is equipped at secondary IDE connector, please assign
this parameter for driver to recognize these hard disks. The valid parameter is
/I14 - Secondary IDE control IRQ14
or
/I15 - Secondary IDE control IRQ15
5. /BKM:xxxx Enable Block mode for hard disk drives
/BKM:abcd
d: Secondary channel slave drive use block mode?
c: Secondary channel master drive use block mode?
b: Primary channel slave drive use block mode?
a: Primary channel master drive use block mode?
For example: /BKM:YYNN
will use block mode for primary master and primary slave drives, and not
use block mode for secondary master and slave drives.
