Hi
Wow… this is really an “stone-age oldie”.

The 32MB of memory is definitely not enough to run the XP!!!
The notebook could be upgraded up to 160MB (32MB internal + 128MB external memory)
In my knowledge the 128MB PC 100 SDRAM memory module PA3005U could be used. I think you will be able to run the XP with 160MB memory.
But in my eyes this is nonsense! The XP will run but the performance would be incredible slow.
Additionally the Toshiba drivers site does not provide any XP drivers!!
I think it make no sense to install Xp on this notebook
