Lh C:\dos\smartdrv.exe 2048

LH = LoadHigh. LoadHigh loader en dosdriver i "extended Memory" i stedet for den konvensionelle hukommelse (under de 640Kb).

SmartDrive er et harddisk cache program, og den sættes så op til at bruge 2Mb som cache.

Loadhigh (Lh)
Loads a program into the upper memory area (UMA). Loading a program into the UMA leaves more room in conventional memory for other programs. Use the systemroot\System32\Config.nt file, or the equivalent startup file specified in a program's PIF, to specify the programs to load high.

loadhigh [drive:][path] filename [parameters]

lh [drive:][path] filename [parameters]

Parameters

[drive:][path] filename

Specifies the location and name of the program you want to load.

parameters

Specifies any command line information required by the program.

SmartDrive er rent et Dos (Win9x) produkt, så den har jeg ikke noget direkte på. Jeg søger lige på nettet.
