RAMDRIVE.SYS--Examples To create a RAM drive in extended memory and allocate 64K (the default amount) of extended memory to RAMDRIVE.SYS, add the following line to your CONFIG.SYS file: device=c:\dos\ramdrive.sys /e This command loads RAMDRIVE.SYS from the C:\DOS directory. Suppose you want to install RAMDRIVE.SYS in expanded memory and allocate 4 MB (4096K) of expanded memory to the RAM drive. To do this and to specify that RAMDRIVE.SYS is located in the DOS directory on drive C, add the following line to your CONFIG.SYS file: device=c:\dos\ramdrive.sys 4096 /a Now suppose you want to allocate 2048K of extended memory to RAMDRIVE.SYS and create a RAM drive that has 512-byte sectors and a limit of 1024 entries in its root directory. To do this and to specify that RAMDRIVE.SYS is located in the DEVICES directory on drive D, add the following line to your CONFIG.SYS file: device=d:\devices\ramdrive.sys 2048 512 1024 /e
