I'm trying to install Windows 7 on a Compaq Presario 2100 laptop with 1GB of RAM and known good HDD. I ran memtest 86 for 12 hours with no errors. The BIOS sucks and has no options for ACPI, power management, or even serial/parallel port addressing, only boot order, system info, and password. The only device option in the BIOS besides video memory (tried every setting there) is legacy usb support (tried that too). I've been googling for 2 hours about this and found the whole F5 and F7 thing for XP, but I'm not sure if there's a similar option in 7 to only use Standard HAL. There's no Press F6 prompt in 7 install to press F7 at.
