30 Gig limit

Is it possible to partition a 60 gig drive into two 30 gig partitions on a new machine. Then install the drive into an older machine which has a bios limit of 30 gig and have it recognize the two partitions. Currently the only way I’ve found is to use a jumper on the drive that limits it to 30 gig wasting the other 30. I can’t find a new bios.
