Motherboard: MS-6153VA

Today I’m looking at a Socket 370 board that would have been made roughly in 1999-2000. It was an interesting period as much of the early legacy technology such as the ISA bus was fading out, marking the beginning of the end for complete backwards compatibility. It is also close to the end of configuring major component with jumpers, replaced with auto-detection and software control. Although this particular board still has a few jumpers.

It’s a MS-6153VA made by MSI, a manufacturer known for making  boards with gaming and over-clocking in mind. It seems they were one of the first to offer over-clocking as a feature quite early in the history of PCs. Surprisingly it was a 286 mainboard, a time when overclocking meant replacing the crystal oscillator. They still cater to the over clocking market with a series of boards dedicated to it.

Here’s an overview of my board.

It’s remarkable because there are actually two boards with the same model number that differ significantly. This board has a VIA chip-set and is marked MS-6153, but if you search for that online you turn up a board that looks almost identical but has an Intel chip-set instead. The model number used in online references is MS-6153VA for the VIA chip-set. This must have caused some confusion at the time.

IMG_2492Here’s something different, 4 LEDs to indicate the current status of the system. If there was a problem they could use these instead (or in addition to) the standard BIOS beep codes. It wasn’t something you’d find commonly, but was extremely useful if you were lucky enough to have a visual indication. Some manufacturers took it further, using two 7 segment displays instead.

IMG_2493Like a previous Socket 7 board, this has a thermister mounted in the middle of the CPU socket. They’ve used a different package, a small flex with the component built in. I’m guessing they did this in an attempt to get a better reading closer to the CPU.

The chip-set is a VIA Apollo Pro 133A, which would have been quite decent for the time. Around the main chips are some of the reference silk-screen, which are quite handy, but are unfortunately quite distant from the jumpers they are a reference for! This may have been necessary due to the layout of the board, and I’m sure the manual would tell you where to find them, but it is annoying as it seems to effect every single silk-screen reference.

Speaking of the manual, I was able to find a download on the MSI website, however it was in the form of a EXE file! Since I’m using my Mac book I wasn’t able to easily open it, bad form MSI.

IMG_2497Next to the floppy connector is a connector that seldom got use in desktop machines. It’s an infrared header! Wireless technology had yet to really evolve into what it is today, and a cheap and simple technology commonly used was infrared, still used today in TV remote controls. It wasn’t commonly used mostly because IR (as it’s commonly called) relies on direct line of sight, and can easily be interrupted. These IR devices were usually treated as a serial port, so software like hyperterm was usable with them. In use they usually proved to be slower and less reliable than just using a cable.

From a technicians view-point it’s also fairly decent, it supported Intel and Cyrix chips up to 800Mhz which was decent for the time. It could also support the large 256Mb SDRAM sticks running at 133Mhz, allowing for a maximum of 768MB of RAM. There are also some rudimentary overclocking features on the board. The main annoyance is with the silk screen reference being so distant from the jumpers, and not having very descriptive names. Still, you could set this up without the manual.

Feature wise this board would have satisfied most end users, although audio and ethernet isn’t integrated. At that point in time integration hadn’t become the norm for those. Luckily there are plenty of PCI and ISA slots so it wouldn’t have been much of an issue. With the right CPU, RAM and GPU it probably would have even made a decent gaming rig for the time.

    I’m not sure but I suspect the .exe file is simply a self-extracting .zip file. If you rename it as .zip, or use a ZIP program to open it directly, you should be able to extract it, as the SFX is a short stub program that sits before the ZIP header which many ZIP programs can easily ignore.

    I think I’ve also got one of these boards myself somewhere in storage – definitely a handy board and the VIA Apollo Pro 133A was definitely one of the better chipsets when it came to versatility and performance.

      Yeah, probably true, I didn’t think of that at the time. It’s still not a great way to distribute a manual as virus checkers and other security measures may block the download. Especially now with browsers being more aware of stopping people from downloading shoddy EXEs.

      One of these days I ought to use this board to build a win9x gaming rig, it seems like it would be a decent performer and probably has support for all the hardware I have lying around.
