Routine Description:
|
|
|
|
Present a menu of formatting options and allow the user to choose
|
|
among them. The text describing the menu must already be present
|
|
on-screen.
|
|
|
|
The user may also press escape to indicate that he wants to select
|
|
a different partition.
|
|
|
|
Arguments:
|
|
|
|
AllowFatFormat - TRUE if the option to format the partition to
|
|
FAT should be presented in the menu.
|
|
|
|
AllowNtfsFormat - TRUE if the option to format the partition to
|
|
NTFS should be presented in the menu.
|
|
|
|
AllowConvertNtfs - TRUE if the option to convert the partition to
|
|
NTFS should be presented in the menu.
|
|
|
|
AllowDoNothing - TRUE if the option to leave the partition as-is
|
|
should be presented in the menu.
|
|
|
|
AllowNtfsFormat - TRUE if the option to format the partition to
|
|
NTFS should be presented in the menu.
|
|
|
|
AllowConvertNtfs - TRUE if the option to convert the partition to
|
|
NTFS should be presented in the menu.
|
|
|
|
Return Value:
|
|
|
|
Value from the FormatOptions enum indicating the outcome of the
|
|
user's interaction with the menu, which will be FormatOptionCancel
|
|
if the user pressed escape.

Routine Description:
|
|
|
|
Determine whether there is a valid disk partition suitable for use
|
|
as the system partition on an ARC machine.
|
|
|
|
A partition is suitable if it is marked as a system partition in nvram,
|
|
has the required free space and is formatted with the FAT filesystem.
|
|
|
|
Arguments:
|
|
|
|
SifHandle - supplies handle to loaded setup information file.
|
|
|
|
Return Value:
|
|
|
|
Pointer to a disk region descriptor for a suitable system partition.
|
|
Does not return if no such partition exists.
