Fernando, I've tried everything, I'm trying for a month, but can not in any way. --- http://forums.toshiba.com/t5/Windows-Vista-Windows-XP/Windows-XP-on-Portege-Z835-P330/td-p/307886 http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=266981 --- There must be some trick to install Windows XP on Z835. What I did was basically the following, the last time I tried: I joined your driver with nLite using a clean Windows XP CD; then, I recorded the system with its built-in driver in flash memory, using FlashBoot 2.1s. The XP installation starts normally, but it is interrupted at a given time: the BSOD appears, accusing the 0x7B error. Nor is realized with the FDD F6 install: the message that appears is of the txtsetup.oem file is not found. Cheers, thanks for listening.
