VDISK.SYS
This driver configures some of the unit’s available random access memory
(RAM) as a read/write disk, called a RAM disk. This driver is located on Drive
B
of the Falcon unit and is loaded using the
config.sys
file located on that
drive. On
31x
models, all of the Extended Memory on the unit (either 1 or 3
MB) is used to create a single disk (Drive
D
). On all other models, only the first
1MB of Extended Memory is used to create Drive
D
. The remaining available
Extended Memory may be used to create additional RAM disks.
