The biggest downside with this Toshiba, for me, was the only available o/s was Windows 7. Unfortunately, I use a lot of apps that require Windows XP, so an XP downgrade was necessary. Looking around the net there were really no guides to performing the downgrade, just a lot of people looking for assistance. After a few hiccups, and a lot of searching for drivers, XP is now installed with 99% of the hardware working.
The first step was to get an SSD installed. The Toshiba came from the factory with a 5400RPM hdd. Put simply, the SSD option was just way overpriced, so an SSD was purchased separately. The install, though voiding the warranty, was fairly straight forward besides the fact some new tools were needed: a small torx wrench and some needle nose vice-grips. The need for vice-grips was because I managed to strip one of the screws attaching the HDD.
The first thing to get XP installed is to get SATA drivers working in XP. While most OEM versions of XP (from Dell, Asus, etc..) have sata support they're sketchy at best with the direct to consumer xp releases. I choose to slipstrean the drivers into a custom XP install using nLite. Details on this are another how-to unto itself; google is your friend here.
Now that XP is sata aware there is one other adjustment must be made before XP can see the ssd. In the BIOS of the Toshiba sata support must be set to compatibility mode. After that is done the WinXP Installer should recognize all sata disks.
Getting all the hardware working was just a matter of combing the net for compatible drivers. Below is a synopsis of each piece of hardware followed by a link to download them all in a rar file.
this was the easiest, just went to ATI's site and downloaded xp drivers for the Radeon HD 3200.
found drivers for the RTL8187se chipset at Realtek's site
Athereos ar8132 from MSI's site.
Sound: partially working
got the contexant chipset drivers from Toshiba's site from a notebook that had xp downgrade options. yet to try and get HDMI audio working; I'd rather the thing had a PC Express card slot instead of an HDMI port.
SD reader: working
got really lucky with this and tried some Realtek drivers that worked.
here is a rar file containing all the drivers mentioned above. Hope some you who were having trouble find this.
P.S. if you'd like to run Linux, the Ubuntu install works out of the box after the restricted drivers are enabled.
