- ACPI PC
- Completely PnP and handles the configuration of your devices(PnP) and gives you no control. It can solve most resource conflicts. If a conflict happens then it has be fixed in BIOS or changing addon cards.
- Includes power management, so if having a laptop it will help on battery time
- Doesn't show the actual hardware IRQ's the different devices uses, instead it has one of these behaviors:
- It looks like all devices are sharing the same IRQ, but it just means they are controlled by the same ACPI Controller
- It looks like all devices have their own IRQ, but assigned IRQ is an software IRQ (>15)
- Standard PC
- Includes some Plug'n'Play (PnP) but still allow you to configure your devices. There is a higher chance of resource conflict, but you might be able to solve it in Windows before going into BIOS.
- Limited power management features, and for some motherboards it gives better performance and less conflicts
- Will show the actual hardware IRQ's the different devices are using
- Go to "System Properties" in Control Panel
- Select the tab "Hardware" (Press the button "Hardware Profiles" to make a backup before continuing)
- Press the button "Device Manager" (Will bring forth a tree)
- Find the node "Computer" and expand
- You should now see a component called "Advanced Configuration and Power Interface (ACPI) PC"
- View component properties (Double click the component)
- Select the tab "Driver"
- Press the button "Update Driver..."
- Select the option "Display list of the known drivers..."
- It will now show the current driver for the component
- Select the option "Show all hardware of this device class"
- It will now show different types of computers
- Select the driver "Standard PC"
- It will now redetect all your hardware
Note it is possible to specify what HAL Windows should use during the install, instead changing HAL after the install, and is most likely the best way:
- One way is to edit the file "C:\Txtsetup.sif"(It is made during the textual part of the install process) by setting:
ACPIEnable = 0 (Disabled = 0, Enabled if ACPI BIOS = 1, Enabled if certified ACPI BIOS = 2, Default = 2)
- Another way is to Press F7 when Win2k install says "Press F6 if you need to install a third party SCSI or RAID driver". It will not give any confirmation of that you pressed F7, but it will not use ACPI.
- Yet another way is to press F5 instead of F7. This will bring forth a menu where
it is possible to select from a whole range (Might have to press arrow-up/down to see them all):
HAL File Description Standard PC Hal.dll Any Standard PC, non-ACPI and non-MPS (Usually 386, 486, Pentium, Pentium II, or Pentium III) ACPI PC Halacpi.dll Applies to a single processor motherboard with single processor (Pentium 4, Athlon) ACPI Multiprocessor PC Halmacpi.dll Applies to a multiple-processor ACPI computer. ACPI Uniprocessor PC Halaacpi.dll Applies to an ACPI multiple-processor board but with a single processor installed. MPS Multiprocessor Halmps.dll Applies to non-ACPI computers with a dual processor running. MPS Uniprocessor Halapic.dll Applies to non-ACPI computers dual processor motherboard with a single processor installed.
