Yes.  I read that as a 294GB hard drive.  Under FC1, the calculations
are done for you:

[root at prophead tmp]# fdisk -l /dev/hda

Disk /dev/hda: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot    Start       End    Blocks   Id  System
/dev/hda1   *         1       131   1052226   83  Linux
/dev/hda2           132      5353  41945715   83  Linux
/dev/hda3          5354     10575  41945715   83  Linux
/dev/hda4         10576     19929  75136005    f  Win95 Ext'd (LBA)
/dev/hda5         10576     11097   4192933+  83  Linux
/dev/hda6         11098     11228   1052226   82  Linux swap
/dev/hda7         11229     19929  69890751   83  Linux
