As you increase or decrease the ROM Disk Size: setting,

the Minimum ROM Disk Size: as well as the Memory

Allocated For ROM: and the Memory Available For

RAM: settings adjust accordingly.

Select the size ROM Disk you want and press return. (For a discussion of how much memory should be allocated to ROM, see, Memory Allocation.) If you have more than 2 Meg of memory installed, see, “More than 2 Meg” in the previous section.

*Important: Resetting the ROM Disk size will, in effect, “cold boot” your computer. So, while files in your ROM Disk will remain untouched, anything you might have stored in your RAM Disk will be erased. If you didn’t save your RAM

Disk contents and you want to, press to back out of this menu and save the RAM contents to disk before returning to this menu.

More than 2 Meg

Those using more than 2 Meg of memory may come across an easily surmountable obstacle. ProDOS allows bit map blocks in increments of 2,048K (4,096 blocks). If you find that you cannot increase your ROM Disk past a certain size, it has probably stopped at a multiple of 2,048K. If you want to go above that, you will need to reinitialize your ROM Disk for more than that multiple of 2,048. For instance, if you set the ROM Disk size to 2,049, then initialize, you can change your ROM Disk size to any setting from 4K to 4,096K. If you set your ROM Disk to 4,097K, you’ll have a range from 4K to 6,144.

ROM Disk Memory Test

Use the ROM Disk Memory Test to test the memory used

by the ROM Disk without destroying the contents of that memory.

This a quick test that will run as soon as you select the option from the RamKeeper main menu.

While the test is running, bar graphs will show you the test’s rapid progress through two passes.
