AMD K6-2 Tower
AMD K6-2 was a processor released mid-1998 as AMD's response for Intel's Pentium Pro and Pentium II architectures. These CPUs had 3DNow instruction set making it more powerful in some applications. This is a ca. 1998 machine with K6-2 processor and Tseng ET6000 video card - a PCI board which had better performance than typical S3 ViRGE these times, and in text mode display was just unbeatable. Additionally it has a hard drive drawer for backups. Unknown "G&B" sticker is present on casing.

It's a PC, with AMI BIOS, but in many revisions without this famous AMI BIOS Setup GUI. It starts normally.
If you want to run faster processors, you have to use undocumented jumper settings. As it is not Super Socket 7, it will not run at 100MHz, only at 83MHz which is sufficient for many AMD processors and even may allow some overclocking (generally many AMD K6-2 and K6-3 could work well when overclocked a bit, but mainboard and RAM have to be good). The most important thing is multiplier settings, these additional undocumented settings are following:
|Jumper settings for PC-Chips M575 (and clones) for newer CPUs|

The CPUs won't overclock or the external cache will not work.
But if you still see a lower frequency than set with jumpers, you have to upgrade BIOS. BIOS upgrade procedure is typical as in many PCs, and as result you may get detectable CPU. Contrary to information above, some small overclocking is possible, but don't expect jumping 100MHz more.
Tseng ET6000 is a video board which has drivers in Win9x and they should be installed with OS. If you plan to try with Linux, it's worth as this board is really fast in high-resolution text modes.
