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.
