I am trying to use a disk image which I created using qemu for Bochs. I am having some issues in figuring out the geometry of the disk. Bochs requires that I specify
a) the number of cylinders
b) the number of heads
c) the number of tracks

When I do fdisk -lu fc5_3.0.2.img I get
------------------------------------------------------------------------------------------------
last_lba(): I don't know how to handle files with mode 81a4
You must set cylinders.
You can do this from the extra functions menu.

Disk fc5_3.0.2.img: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders, total 0 sectors
Units = sectors of 1 * 512 = 512 bytes


        Device Boot      Start         End      Blocks   Id  System
fc5_3.0.2.img1   *          63    10490444     5245191   83  Linux
fc5_3.0.2.img2        10490445    12578894     1044225   82  Linux swap / Solaris
------------------------------------------------------------------------------------------------

When I boot up the disk using qemu and do fdisk -lu /dev/hda from *inside qemu*, I get
------------------------------------------------------------------------------------------------
Disk /dev/hda: 6442 MB, 6442450944 bytes
255 heads, 63 sectors/track, 783 cylinders, total 12582912 sectors
Units = sectors of 1 * 512 = 512 bytes


        Device Boot      Start             End       Blocks   Id     System

/dev/hda2           10490445    12578894    1044225    82     Linux swap / Solaris
------------------------------------------------------------------------------------------------


I tried using the geometry as seen inside qemu (783/255/63) in bochs but bochs fails with the message
[HD   ] ata0-0 disk size doesn't match specified geometry


Any ideas how I can use this disk. The only other option is to create a disk using bochs from scratch - which I would like to avoid.

Any help is appreciated.
