Chapter 6, Memory Cards/Mass Storage
Using RAM Disk
Initializing RAM Disks
Each RAM Disk unit must be initialized before it can be used. Unit 0 can be
initialized using the RAM_MNG procedure stored on internal ROM Disk.
Volumes 1, 2, and 3 must be initialized from the TESTS (IBASIC Controller)
screen.
The optional “unit size” parameter in the following procedure specifies the
memory area, in 256 byte blocks, set aside for each disk unit.
Follow these steps to initialize volumes 1, 2, or 3:
1. Access the TESTS (IBASIC Controller) screen.
2. Using the rotary knob or an external terminal, enter and execute the IBASIC command:
INITIALIZE ":MEMORY,0,<unit number 1-3>",<unit size>
For example:
INITALIZE ":MEMORY,0,1",50
The IBASIC INITIALIZE command defaults to LIF format. Any media (RAM Disk,
SRAM Cards, External Hard Disk Drive, or 3.5-inch floppy) formatted using the default
conditions of the INITIALIZE command will be the LIF format and will be unusable in
the Test Set , except for IBASIC mass storage operations. Refer to "Initializing Media
for DOS or LIF File System" on page 362 for information on formatting media for the
DOS file system.
