RAM Disks
There are three steps to sec up and use a RAM disk:
1. Use the MultiRam disk utility in create the RAM disk.
2. Copy the desired programs and files to it.
3. Choose and run a program on the RAM disk.
The DOS 3.3 and ProDOS RAM disk creations are the only choices from the
Main Menu to be discussed in this chapter.
DOS RAM Disk
When using the DOS 3.3 RAM disk you must have the DOS system master
and two DOS formatted disks ready. Using DOS 3.3 RAM disks is not
encouraged due to the many limiting factors of DOS 3.3.
Without going into too much detail, let’s look at some of the limiting factors
of DOS 3.3. Each DOS RAM disk is limited in a 384K size and no more
than nine disks can be made. A MultiRam ROB with 1 megabyte may be
setup with three DOS RAM disk. These RAM disks will, by default, be put
into slot 3 as drives 1.2 and 3. Another limit of DOS is that no more than
105 files may reside on a disk, even if all the memory of that disk has not
been used. DOS 3.3 does not have an effective way of handling a large
number of files. ProDOS’s structured directories and subdirectories make the
managing on hundreds or thousands of files easy.
Setting up a ProDOS RAM disk requires the three major steps mentioned
above. However, creating the DOS RAM disk will take approximately twenty
steps. Chapter 7 in the “MultiRam Software Manual” outlines the procedure
for making and using the DOS 3.3 RAM disk. Please use the ‘MultiRam
Software Manual” when using DOS 3.3 RAM disks.
ProDOS RAM Disk
The submenu that appears from the Main Menu shows several ways to
customize the RAM disk.
1. Install the RAM disk using the preset slot and size.
2. Change the slot and the memory size of the RAM disk.
3. Go back to the Main Menu.
