The trick only works if I've owned the board for at least 25 years.
Still, it could be a slightly different model. I know there is one fairly close that has a Weitek socket instead of a 487SX socket, but the exact name escapes me.
Your board has a sticker that has "FEAT5030" printed on it.
TH99 has a board labelled FEAT 5031. I think FEAT is actually the model of the PC. The real board model name should be PKM-5031Y (which I think is just PKM 0031Y with slightly different equipment). So, it's possible that your board should be an older version not listed on TH99....perhaps a PKM-0030Y?
DTK wasn't just any old white box PC vendor. They actually made their own shit, and they made TONNES of it. I wish I had some documentation to decipher their model names.
If we use PKM-0031Y as an example, I believe the 'M' stands for motherboard. Not sure what the 'P' and 'K' are, but the 00 is a place holder for the operating speed of the unit sold. So 3331Y is a 33MHz version, and 5031Y is the 50MHz version. They usually slap a sticker over base model name after the CPU has been installed. The last letter in the code is the manufacturer of the chipset. Y is for Symphony. S is for SiS. P is OPTi. C is for C&T. V is for VLSI. I is probably intel....and I think no letter indicates discrete logic (no chipset).
