Windows XP on the XO-1 loads and works just about the same as on any other
machine. Microsoft did the implementation, primarily by replacing Open
Firmware with Insyde BIOS, a standard proprietary x86 PC BIOS. There’s nothing
you’d learn from it that you wouldn’t learn from studying XP booting on any
other PC.
Windows XP on XO-1.5 was made available in a dual-boot configuration,
supporting Sugar and XP. That work was done by OLPC, mainly by Mitch Bradley
and me, and the system booted from Open Firmware. The Open Firmware work
consisted of adding support for required PC BIOS interfaces, and much of the
rest of the technical work involved supporting Microsoft’s modifications to
allow XP to be booted from removable media (a card in the external SD slot).
Microsoft did not support booting XP from removable media, and at the time the
XO-1.5 was the only machine that could do so - as far as I know, that’s still
the case. But there is nothing to learn there other than how Mitch and I
implemented Microsoft’s cryptic and often unhelpful suggestions to get it to
work. In particular, XP on the XO-1.5 is locked to a specific SD card
signature so no other make and/or model of SD card would boot. Reasonable
effort went into that fairly useless exercise.
And as Paul says, in each case these machines were made available for initial
trials by a specific customer and were never generally available or widely
produced.
