Which HAL?
Quick way to check: Update your BIOS to the latest version! (With a few exceptions,
ie of AR440BX boards, where Intel LOCKED out P3 processor upgrades. But these are
x440BX boards, circa 199x) - Enter Setup and turn on any new options for APIC and
ACPI.
Boot from the W2K or XP install CD, and press F5 when it says to press F6. Wait until
prompted for HAL option. For a single processor PC: one KNOWs Standard PC will work.
StndPC is the fallback if the following doesnt work: Choose ACPI PC/Advanced Configuration
Power Interface PC, NOT ACPI Uniprocessor PC. See if setup continues past 'Starting
Windows 2000' or 'XP'. If the computer does not freeze, exit setup. If it freezes,
use Standard PC.
ACPI PC works:
When the computer restarts, go through the same step and choose ACPI Uniprocessor
PC. If setup gets past 'Starting Windows 2000/XP', continue.
If you are trying to switch HAL's, the only/best way I know is to do a repair of
windows, using the method above.
Oldest PC to Current models;
Standard HAL - Standard PC
Works well on all pre-ACPI PC's, and most early ACPI PC's. (BIOS prior to late 2000)
For Laptops and those desktop PC's which have drivers written to permit IRQ sharing;
Advanced Configuration and Power Interface PC or ACPI PC (varies on the language
of windows). DO use this HAL if one has a PC where power management is a critical
issue, such as a laptop, or a desktop. DO NOT use this Hal if the desktop sound seems
to stutter, or network performance is noticibly slower, video frames per second/performance
is noticibly slower. TRY to skip using this HAL as it does not support APIC, where
the PCI and AGP IRQ's are individually set per item (network card, audio card, onboard
PCI audio and network, USB) distributed from IRQ 16 through to ~27. This HAL has
the advantage of giving better power management support (lower power consumption
and more intelligent power management interface) on computers whose BIOS cannot be
updated past Y2K compliance, about late 2000.
APIC is the Advanced Programmable Interrupt Controller. ALL APIC PC's (check in BIOS
or specs) are ACPI-compliant.
