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.
