BIOS disk geometry and Linux 2.6
I am working on a Linux-based boot disk for my project
(http://unattended.sourceforge.net/), and I have hit a snag.
Under Linux 2.6, the kernel (via HDIO_GETGEO) always reports the C/H/S
geometry of an IDE drive as X/16/63. But most BIOSes want to use the
geometry Y/255/63.
Most partitioning tools (including Parted) will take clues from an
existing partition table and adapt to the BIOS values.
