FreeDOS help system (hhstndrd 1.0.8 en)[lastdrvh]

Command: lastdrivehigh

Lastdrivehigh is a CONFIG.SYS / FDCONFIG.SYS command. Lastdrivehigh sets the last letter to which a drive can be assigned.


lastdrivehigh=x where x is the last letter that will be available.


- none -


By default, FreeDOS will set x high enough for all floppy drives and detectable hard drive partitions, plus one for a CD or other drive. You may want to set x higher if you wish to use more than one drive that FreeDOS cannot detect automatically (CD drives, zip drives etc.). Setting x higher than necessary wastes a small amount of memory. LASTDRIVEHIGH is like LASTDRIVE, except it attempts to load into high memory first (failing that it should load in conventional memory). Note: The order you load devices may have a large impact on amount of free memory available. In general try to load large (in memory usage) programs into high memory first. Important: You should have a high memory manager such as (HIMEM), HIMEMX or JEMMEX installed (prior device=himem.exe or device=himemx.exe in CONFIG.SYS / FDCONFIG.SYS) before using this option. LASTDRIVEHIGH is a command internal to kernel.sys and needs no other file in order to work.


IN CONFIG.SYS / FDCONFIG.SYS: lastdrivehigh=z enables drive letters from A - Z.
