Routine Description:
|
|
|
|
This routine does a FAT format on the given partition.
|
|
|
|
The caller should have cleared the screen and displayed
|
|
any message in the upper portion; this routine will
|
|
maintain the gas gauge in the lower portion of the screen.
|
|
|
|
Arguments:
|
|
|
|
Region - supplies the disk region descriptor for the
|
|
partition to be formatted.
|
|
|
