HAL explained on the Sista's: By default when you install Winblow's on a Sista the HAL (Hardware Acceleration Layer) defaults to ACPI Uniprocessor PC.
Hardware Accelaration Layer. This is the code that produces the interface between the hardware and any software using it, for example, a graphics adapter, and an API.
For some reason XP defaults to ACPI Uniprocessor PC during a fresh install of Winblow's on the Sista's. ACPI Uniprocessor PC applies to an ACPI multiple-processor motherboard that's running with a single processor installed. Now obviously, the Sista's aren't MultiProcessor boards Using this HAL has been known to cause issues for a lot of users.
Advanced Configuration and Power Interface (ACPI) PC applies to a single processor motherboard running with a single processor. THIS is the one you want installed on a clean install of Winblow's. You need to install it manually when doing a fresh install of XP by pressing F5 when it asks you to press F6, if you wish to install Sata Raid drivers then press both the F5 and F6 keys at the same time, when prompted. You will be asked during the install for which HAL you would like to choose from. Use the arrow keys on your keyboard to SCROLL UP AND DOWN to select Advanced Configuration and Power Interface (ACPI) PC from the list.
You can also choose to change the HAL to Advanced Configuration and Power Interface (ACPI) PC
with Winblow's already installed, its not recommended though as a lot of users have problems trying it this way. What you do is, right click
My Computer/Properties/Hardware/Device Manager/Computer,
highlight the ACPI Uniprocessor PC, right click and choose Update Driver.
Click "No Not This time".
Next. "Install from a list or specific location (Advanced)"
Next. "Dont search i will choose the driver to install"
Next. Choose "Advanced Configuration and Power Interface (ACPI) PC"
Next. The new HAL will install and you will be prompted to reboot, upon reboot you might find your puter will stick at the Winblow's screen, if you try rebooting and it keeps sticking at the Winblow's screen then try booting in safe mode and then rebooting again normally. If you still don't get a normal boot then its a good chance your setup doesn't like the new HAL, and the only way you will get it to load properly is to do a clean install of Winblow's and follow instructions above.
Here is a list of all the HAL's and what they are for:
â€¢ ACPI Multiprocessor PC
Applies to a multiple-processor ACPI computer.
â€¢ ACPI Uniprocessor PC
Applies to an ACPI multiple-processor board but with a single processor installed.
â€¢ Advanced Configuration and Power Interface (ACPI) PC
Applies to a single processor motherboard with single processor.
â€¢ Compaq SystemPro Multiprocessor or 100% Compatible
Applies to a Compaq SystemPro computer.
â€¢ MPS Uniprocessor PC
Applies to non-ACPI computers dual processor motherboard with a single processor installed.
â€¢ MPS Multiprocessor PC
Applies to non-ACPI computers with a dual processor running.
â€¢ Standard PC
Applies to any Standard PC, non-ACPI, or non-MPS. The CPU may be a 386, a 486, a Pentium, a Pentium II, or a Pentium III.
â€¢ Standard PC with C-Step i486
