r
The 5555 option specifies the sector size in bytes. The default
value is 128 bytes. The following values are allowed: 128, 256,
^ 512, and 1024 bytes.
The dddd option specifies the number of root directory entries.
The default value is 64; the minimum, 2; and the maximum, 1024.
\) Ramdrivesys adjusts the value of dddd to the nearest sector
^~ boundary. For example, if you give a value of 25 when the sector
size is 512 bytes, the 25 will be rounded up to 32, since 32 is the
r^\ next multiple of 16 (there are sixteen 32-byte directory entries in
512 bytes).
The /e switch lets you use extended memory (above 1 megabyte)
r^\ as a RAM disk if it has been installed. If you use this switch, you
cannot use the /a switch.
The /a switch lets you use an extended memory board that meets
r^\ the Lotus/Intel/Microsoft Expanded Memory Specification for a
RAM drive, if that board has been installed. If you use this switch,
you cannot use the /e switch.

Note When you reset or turn off the power on your computer,
^^ any information stored in RAM disks is lost.
