Managing partitions using GDisk 77
Support for large hard-disks
GDisk includes large disk-drive support for IDE and SCSI hard drives (disks that
exceed the 1024 cylinder BIOS limitation, which translates to a capacity greater
than 7.8 GB). GDisk can directly access hard disks through the IDE controller or
ASPI interface provided by an ASPI driver. Take care when creating partitions
for operating systems with inherent partition-size limitations.
