Drive letters (A: through Z:) are assigned to all hardware that can be used to store data or programs (i.e. diskettes, cd-roms, disk partitions, remote disk partitions). With the addition of RESERVEDRIVELETTER, you now have the ability to control some of these drive letter assignments by reserving 1 or more consecutive drive letters during the earliest part of system initialization.

note: In Warp 4 you can assign this option with the Reserved page of Drives - Properties. Your config.sys will automatically be updated with the values you specified.

Reservedriveletter=Drive

Parameters:

• Drive

  CDRom, Optical drives, Virtual disks and Tape drives gets driveletters beginning with the NEXT letter you have defined with Reservedriveletter. You can not change the driveletter for harddisk partitions. For example you have a harddisk with two partitions and one CDRom drive. Without Reservedriveletter set up the harddisk partitions will get driveletter C: and D:, the CDRom will get driveletter E:. If you want your CDRom to become drive G: you should use Reservedriveletter=F.
  Drive can be in the range from D to Y .
