би трябвало да може ако се изключи ACPI по време на инсталацията, но не съм имал под ръка 486 със 64mb че да опитам:

[url=http://www.logan.eclipse.co.uk/xp%20hints%20&%20tips.htm]To disable Acpi when installing Win XP then you should hit the F5 key at the same time when it asks you. "If you wish to install any 3rd party raid SCSI drivers press F6". Only press the F6 with the F5 key if you need to install raid or scsi drivers. Otherwise just the F5 key, this is important and you will only have about 5 seconds to do this so pay attention. If you miss the moment then reboot and try again. If you get it, then a menu will open up that you can pick your computer from. There you have two choices: Standard PC and 486 with Stepping. Select 486 with Stepping and voila no ACPI will be installed.[/url]

Просто не знам защо ще им е опция "Standard PC and 486 with Stepping" ако не поддържат 486...
