Trying to install or upgrade a ThinkPad T60p from WXPPRO SP2 to Vista RC1\n(5600). Boot to DVD and begin install, stops (on the bar scanning back and\nforth) with BSOD STOP 7E ACPI.SYS error. Upgrade does all the normal scan,\ncopy, et al... then reboots, then ditto. Any suggestions? Turned off\nSpeedStep. Same thing.\n\nIt's 2GHz, Dual Core, 1GB RAM, 100GB Drive. 25GB free.
