Bought new mobo and have compatability question about HDD

[Mecha]

Ok i bought a new mobo off of newegg.com, it is the Abit Kn8 sli edition and on newegg.com they state that the mobo has 2 x ATA 100 up to 4 Devices but on the Abit website they state that the mobo has 2 ATA133 for 4 devices and i have a 80gig ATA 100 seagate hard drive and i was wondering if my hard drive would work with this mobo or would i have to buy a new hard drive since mine is too slow. I just dont know cause each site says something different. Help is very appreciated!!

It will work just fine

so even if it was ata 133 and up support on the mobo, it would still work with my ata 100. Are you certain?

An ATA 100 drive will work on an ATA 133 MB
