Toshiba’s website seems to be missing the correct drivers from the download page specifically for this model laptop.
Driver Page: Toshiba A100-ST3211 Drivers
Toshiba has drivers listed for hardware that was not an option on this model and drivers missing for hardware for this model. Better than that, all the drivers show that they are for Windows Vista. This latop came with Windows XP installed on it. As far as I can tell, Vista was not an option at the time this latop came out. Why only drivers for Vista and none for XP?
Toshiba had the laptop specifications listed right on the drivers page from above. The first driver I went searching for was the network driver. Once you have that, you can access the internet to download the other drivers. This isn’t a problem if you are able to download them all ahead of time and burn to a cd or copy to a USB memory stick.
The software modem appears after you install the audio drivers. If it asks you to find agrsm.sys or agrsmsrv.exe, they are located in the C:\windows\system32\drivers\ and c:\windows\system32\ folders.
Sound card issues
After going through the system update and driver insstall process, I encountered problems with the audio driver and xp service pack 3. It is necessary to install the Microsoft KB888111 Universal Audio Architecture (UAA) High Definition Audio class driver before installing the Realtek audio drivers. Microsoft released a version of the UAA drivers for XP service pack 1a and service pack 2, but not for service pack three. In order to install the UAA driver if service pack three is installed, you will need to follow this short how-to:
This patch is required before any of the HD device drivers are installed
- On your PC change the CSDVersion registry key to XP SP2:
- Restart your PC
- Install Microsoft KB888111 Universal Audio Architecture (UAA) High Definition Audio class driver
- Install Realtek High Definition Audio Driver
- Change the CSDVersion key back to XP SP3 again: HKLM\SYSTEM\CurrentControlSet\Control\Windows\CSDVersion value=300
- Restart your PC, finalize configuration of your PC, sysprep and capture.
- Goto Start>Run and type in regedit , then click OK.
- Click the plus signs in front of HKEY_LOCAL_MACHINE, SYSTEM, Current Control Set, Control, and finally, click Windows.
- In the right panel you will see CSDVersion.
- Right click it, choose Modify.
- In the highlighted input window, you should see 300. Change it to 200.
- Click OK, close regedit and restart your PC. Windows will now think it is SP2 and allow you to install the UAA (KB888111) and your HD audio driver.
- Install the Microsoft KB888111 Universal Audio Architecture (UAA) High Definition Audio class driver
- Install the Realtek High Definition Audio Driver
- Make sure to reboot and then test your sound BEFORE, changing the value back to 300.
- Then follow the same steps to change it back to SP3. Change the 200 back to 300. (Make sure to reboot)
