The Tyan Trinity 400
S1854 Via Apollo Pro133A mainboard
Monday, March 13, 2000
The features (continued)
Additional features found with the Tyan Trinity 400 S1854 include: Wake on LAN, Wake on Modem Ring, PS/2 connectors, USB connectors, RX/TX connectors for infrared, Power Failure Recovery, and start-up from the keyboard/mouse/or at a pre-set time. Hardware monitoring of fan speed, and of CPU temperature, and voltages is available only as an option. An integrated sound card which uses the Creative Labs ES1373 chipset is also available as an option. This board meets all the requirements of the PC99 standard.
Below, a photo of the S1854 provides us with a nice view of the board, its components, and their disposition. Note that the model in the photo is one which offers an ISA slot

Installation
Installation of the Trinity 400 S1854 is relatively simple. There is no real need to monkey around with the jumpers that determine the clock multiplier, as most CPUs ignore these settings anyways.
Certain versions of the S1854 included a jumper labeled J21 that should be left open in-order to use FC-PGA processors, though the unit we received for testing did not include it. All things being equal, the only point of tension is in correctly positioning the accessory connectors facing towards the front of the case, as the user's manual is not very clear on the point at first sight.
The software bundle
Tyan was less than generous with the software included with the S1854. In fact, the pack is composed of the VIA 4-in-1 drivers, and a PDF version of the user's manual. A second disk offers a Internet try-out pack, for whatever that's worth...
