User-Specified Memory Size
The user may specify a certain amount of memory to be allocated for
the Save to Disk function. However, the amount of space required to
store all system and video memory is calculated automatically,
whenever the CREATE option is used, even if the user specifies some
desired amount.
If the amount specified by the user is equal to or greater than the
calculated amount, then the user-specified amount is allocated. If the
user-specified amount is less than the calculated amount, then no
space is allocated, and an error message is displayed.
If you wish to allocate a specific amount of disk space for this
function, enter the amount in kilobytes, as a simple decimal number,
without any notation such as K or KB.
/PARTITION or /P
PARTITION creates a hard disk partition where only Save to Disk
data can be stored.
/FILE or /F
FILE creates a file on the hard disk DOS partition that is used to store
only Save to Disk data.
When the system and video memory outgrow the size of this Save to
Disk space, the /FILE option can be used to re-allocate a new Save to
Disk partition, and also eliminates the time consuming task of backing
up the entire hard disk drive before running PHDISK /CREATE
/PARTITION. The Save to Disk file can be a temporary or a
permanent solution.
