The Universal Serial Bus driver will not be recognized by Windows 95 and will show up as an unknown device. You will need Windows 95 OSR2 to support USB. The driver for USB support under OSR2 is supplied by Microsoft. The latest Windows 95 OSR2 version (OSR2.1) already contains this driver.

Due to copyright issues, we cannot supply this driver !

Can I disable my USB controller ?

It is not possible to disable the USB controller on TX chipset based mainboards. The USB controller will thus always occupy an IRQ. The USB controller is capable of sharing an IRQ, however, so if you want to install a device which is also capable of sharing an IRQ they can use the same one without having conflicts.

Under Windows 95 the Intel Busmaster IDE Controller (or) PCI bridge is not installed correctly. How can I solve this problem ?

Please make sure to install the latest BIOS update for your mainboard. If you are not sure whether you have installed the latest BIOS update, then look here for more information. Also install the TX update file to correct the Intel IDE controller installation problem. If after installing the TX update your IDE controller still has problems, then do the following:

1. Go into the Device Manager and select the Intel IDE controller
2. Click on Resources
3. Unmark the checkbox for Use Automatic Settings (= switching to manual)
4. Restart Windows. The problem should be solved now.

Does the 5TDM/5TTM support the 233Mhz AMD K6 ?

Yes, the 5TDM and 5TTM mainboards do support the 233Mhz AMD K6.

Does the 5TDM/5TTM support the new Cyrix M2/6x86MX processor ?

At this moment we are still testing the new Cyrix M2 or 6x86MX processors on the 5TDM and 5TTM mainboards. The expectations are that it can support this processor series. We will release information on this subject as soon as it becomes available in our Chaintech News section. Please check our website regularly for updated information.

Furthermore, a new BIOS update will not be necessary to fully make use of the M2 processor`s potential. Make sure to use the right voltage and frequency settings for your processor.

Can I run the 5TDM0/5TTM0 at 83Mhz ?

The PLL synthesizer on the 5TDM0/5TTM0 does not support a busspeed of 83Mhz.

Can I switch on my PC by a timer in the BIOS ?

Yes, it is possible to let your BIOS switch on the computer at a certain day and time by using the Resume by Alarm option in the BIOS Power Management Setup.

This option can only be used if you have an ATX power supply !

Go into the BIOS Setup, select the Power Management Setup and Enable the Resume by Alarm (left bottom) function. As soon as you enable this function, you can set the day (1..31) and the time (hrs:minutes).

After setting this, exit the BIOS Setup (save settings and exit) and softpower off your system. You can do this for example by starting up Windows 95 and shutting down.

The system will then startup at the day and time you set earlier.

Why does my PC show the wrong speed of my CPU when I press reset ?

The SeePU technology needs some time to detect your CPU. If you press reset before the startup screen appears, it will regard the detection either as correct, but showing the wrong speed, or it will regard the detection as failed and thus return to its original state before the system was setup. This original state will show 110Mhz.

After installing my Seagate 3XXX harddisk I get a lot of read errors. What`s wrong ?

The Seagate harddisk series 3XXX uses 3.5V as signaling voltage. The industry standard for signaling voltage of IDE devices at this moment is 3.3V. When using older chipsets, this 3.5V is still supported, but the new Intel TX chipset has been designed exclusively for 3.3V. This sometimes causes problems when the system load is high and the distinction between the voltage levels of `1` and `0` becomes critical. That is why when formatting the drive, the problems might not be there but only when the system load is high (after running a few tasks simulataneously), the problem becomes apparent. There is no solution for this problem but to change the drive for another type or brand.

Which SDRAM brands can I use on my mainboard ?

In principle it is possible to use any brand of SDRAM module on your mainboard. However, due to various specifications of certain SDRAM modules compatibility problems have been reported. In general, Chaintech recommends to use only original manufactured modules in order to prevent problems.

Incompatibility problems with memory modules mostly show up quite fast after installing and booting your system. Problems can range from hangups during memory counting, initializing the operating system, GPF under Windows 95, etc.

Recommended modules for the are:

Fujitsu (16/32Mb), SEC (16Mb), Siemens (32Mb), Toshiba (16/32Mb)

Though we try to obtain all possible types and brands of memory modules on the market for testing purposes, we do acknowledge the fact that we can never keep up with all the different brands/types out there. If you find your SDRAM modules show incompatibility problems, then please report the brand and type and your mainboard model (including PCB version) to our technical support service.

Thanks in advance for your cooperation.!

Why can I not use a monochrome adapter in my 5TDM(2) mainboard ?

In order to be able to add new useful features to the limited memory space of the BIOS ROM chip, we have removed the support for monochrome adapters.
