Windows XP clean install on Lenovo R61: Selecting the HAL
I'm following the installation procedures on this page. It's going fine, but I'm at the stage of the XP clean install. Looking at the several instruction pages provided for doing this, I've found this page, which says that I should activate a menu while installing that allows me to choose the Hardware Abstraction Layer. It says that I should select the proper HAL using this menu. I've determined that my R61 is ACPI enabled (the device manager lists it as an 'ACPI x86-based PC'.
My question is, do I need to do this? It sounds dangerous and I really don't know what I'll be doing.
My other question is whether there's a trick to activating the menu with F5. I tried once and couldn't get it to work (I subsequently aborted the installation).
