I got myself an Intel 80286 based PC. It has 40Mb hard drive installed. What is the maximum hard drive capacity that this PC can handle?

Depends on which OS you install. – r0ca Feb 2 '11 at 21:38
why! I hope you aren't using that for anything serious.. – Billy ONeal Feb 2 '11 at 21:55
I once installed Vista on a 80286 with a 40mb hdd, and it run like lightning. – squarebear Aug 2 '11 at 11:46
@Shutupsquare: Lol. Beginning with Vista, ACPI is a requirement. No 80286 PC ever had ACPI, 40MB hard drive (which wouldn't even begin to hold 1% of Vista's files) and lack of MFM/RLL/ESDI drive support aside. – LawrenceC Apr 13 '14 at 14:13

Hard to say exactly because the limit is partly BIOS based, but 504MB is a likely candidate.

Good article about the limits here:
