i've seen a couple of posts on this, namely pointing to the RAID driver issue, so i thought i'd post my install comments as i have an m400 and have a stable environment.

before you instal anything on your toshiba m400, go and grab the RAID driver as pointed out in several posts across the internet.  you can get it from here: RAID_M400.  without this you will not be able to even start the setup on your hard disk.  reason?  let's not go into details -- bottom line: you need it.

once you have it here you go...

[note: there is an updated BIOS you may want to do first--not required for vista, but i always like having the latest.  i did experience some BSODs with vista before (none yet with RC1, but i also have the updated BIOS...i can't confirm whether anything was fixed or not, just reporting that i haven't experienced the BSODs since.]

first, i'd recommend getting vista to DVD media.  for me, that is so much easier to have, it's portable, it's not dependent upon a usb drive, etc. i just prefer that type of installation.

second, note that i am an os-purist.  i prefer rebuilding a machine with a new os from scratch...not upgrading, not partitioning, etc.  boot from dvd, format, install.  i've always had best results using the philosophy and i'm not troubled with any left over os residue (yes, i'm not a trusting person for 'upgrades' and 'uninstalls').

plug in your usb key/drive where you unzipped the RAID drivers above. okay, once you have those out of the way, boot to your vista dvd media.  you'll get to the setup screen on the m400 asking you where to put vista on your hard drive.  here is where you'll notice you can't find your hard drive.  hit F6 or click the 'Load Drivers' button on the setup screen.  then navigate to the RAID driver folder and locate the KR10I folder (vista actually does a good job traversing through subtrees, but navigate to it anyway).

once that driver loads, you'll be able to see your drive (it may be marked Drive 1 [where Drive 0 is likely your USB drive/key]).  just make sure you are picking/formatting the *right* hard disk.

here's where it is up to you -- partition or format...make your choice.

once you choose, let vista install -- on my machine (m400 w/2GB ram) it took about 20 minutes or so.  once done you'll go through the normal stuff of setting up a user, time zone, etc.  and then vista will start.

if your experience is like mine, the os will run great.  you should have Aero ("Glass") effects out of the box with the Intel driver that is in-box with vista (v7.x.x.1053) but you'll notice a few things that may not be recognized yet. 

before you do anything, run windows update.  the biometric driver for the fingerprint reader will download as will the modem driver.  okay, done.  now you may notice still a few things out of skew...

  1. mechanical rotation (meaning when you actually move the tablet, it doesn't rotate the view)
  2. tablet pc buttons
  3. Function+F5 doesn't work
  4. 3 unrecognized devices in device manager: mass storage, unknown device 1, unknown device 2

let me shed some light on these.  you should download the toshiba common modules first and install them.  first the mass storage device is the texas instruments SD driver.  one of the unknown devices is the HDD shock protection: DO NOT INSTALL THIS DRIVER, you will BSOD.  the last unknown device is the bluetooth stuff.

you can get them all from here:

for mechanical rotation, download the toshiba rotation utility.

for tablet pc buttons, download the toshiba tablet pc buttons.

for function+f5, download the toshiba Fn5 hotkey utility.

with all those, i have a great running system!

Wow! I had even called Toshiba to ask if they had any beta drivers and they told me they did not. In fact, they tried to get me to download an older bios for my M5 than what I already had.

Thanks for the link!

This is a great guide for any m400 lover!

@Sharad: For the rotation utility (Fn F5) you should download the "Hotkey Display" Utilily.

I don't think there is a utility for rotation.
9/27/2006 9:22 PM | # re: vista rc1/devtools on toshiba m400
I just read from a site that you can just use the old m200 rotation utility. I got it here: http://www.csd.toshiba.com/cgi-bin/tais/su/su_sc_dtlViewDL.jsp?soid=552054

I tried it and it works!!!

I ran through this on my own and failed as I did not specify the correct folder location for the raid driver, following you instructions, Vista install now see a HD to install on, Thanks Much!

"then navigate to the RAID driver folder and locate the KR10I"

What about using he M400 with the docking station (ability to use second monitor) and return from Standby. I've been testing the M400 for months and still have issues when using the docking station -- it doesn't understand the video transfer. I'm also having issues when returning from standby. If you use passwords, you get the sign-in screen. Once you sign-in the screen is a mess. In order to correct this, you must "switch" users back to yourself, then the display works out.

Toshiba has announced their Vista Bluetooth Stack version for November:

Do you have any issus with Vista RTM on the M400 with the machine just "pausing" for lack of a better term, constantly. What I mean by pausing is that you get the blue spinning disc for 5 - 10 seconds and if you click again you will get a program not responding, and then it just pops back to life? It is driving me and a colleague crazy.

adam: Have you enabled drive performance on the hard drive? Go to manage devices. Then expand the hard drive section, right click on the toshiba drive and choose properties -- there is a policies tab -- make sure the "performance" checkbox is CHECKED.

also make sure you are using the latest RAID drivers from toshiba. i experienced some pausing on mine as well, but have not since the latest bios, drivers, and this checkbox.

I had the latest BIOS and RAID controller, but didn't have drive performance enabled. I turned it on earlier today (based on your reply) and it seems to have done the trick.

Thanks for the advice.

I installed all the latest Vista drivers from Toshiba with the release version of Vista Enterprise and I still get one unknown device, location "on Microsoft ACPI-Compliant system". Sounds like something power related. Then I realized, there is no driver package from Toshiba for the Power Management settings. Is Toshiba no longer using their own Power Management program? Any ideas on how to solve this unknown ACPI device? Thanks...

jim: the latest driver set and complete toshiba pack (whatever they call their new driver bundle) worked for me without issue. check the bluetooth driver, the hard drive protection tool, etc.
