Hi
Model number is pmt90e…. well according to Google its Tecra M9
The Tecra M9 is Win XP supported.
On Toshiba European driver page you can find all drivers:
http://eu.computers.toshiba-europe.com -> Support & Downloads -> download drivers
Here choose: Archive – Tecra – Tecra M series - Tecra M9 – PMT90E – Win XP
So now you can see all drivers.
The Intel Storage Manager can be found there… this is needed in order to get the HDD recognized by Win XP.
You can use nLite in order to create an iso and to add the Intel Storage Manager to iso image.
