M-Tech R540 Mbord

[Tbird man]

i have a M-Tech R540 motherboard. i got a cyrix m2 300 75mhz bus from a friend and when i updated my bios to support it and now when i set the jumpers to 75x4(300) it says its an mII 200 bt if i set it to 66x4.5(297) it says its a 300. and if i set it to 75x4.5(337.5) it says its a 233.

is that through the bios u see it flash up like that? cause you should use wcpuid it more accurate and if i were you i would go with 100x3 other than 66x4.5
