VMEM PREFERENCES
The VMem preferences program is added to your system in the "Prefs"
drawer of your boot disk. From this program, all features of the VMem package
can be controlled by simply selecting the gadgets.
When you run VMem,you will see a window with gadgets for the
following options:
NOTES :
* Many of these options are for advanced users,and could
(and should) be ignored by novices.
* Help is available in the VMem Prefs program by pressing
the Help key, or clicking the right mouse button while
the mouse pointer is over a gadget.
Fast: This option allows you to set the FAST memory
emulation mode. Clicking the gadget (or Holding the
right Amiga-Key and pressing F) will toggle between
the following :
FAST: Sets VMem to cause all attempts to
allocate FAST memory to use FAST
memory . (This is the normal mode)
CHIP: Sets VMem to cause all attempts to
allocate FAST memory to use CHIP
memory instead.
PUBLIC: Sets VMem to cause all attempts to
allocate FAST memory to use PUBLIC
memory instead. (This is probably
the best option for an Amiga without
FAST memory installed.)
Chip: This option allows you to set the CHIP memory
emulation mode. Clicking the gadget (or Holding the
right Amiga-Key and pressing C) will toggle between
the following :
FAST: Sets VMem to cause all attempts to
allocate CHIP memory to use FAST
memory . (This is a very dangerous
option - don't use unless you know
what you're doing !)
CHIP: Sets VMem to cause all attempts to
allocate CHIP memory to use CHIP
memory. (This is the normal mode -
You should probably leave it alone.)
PUBLIC: Sets VMem to cause all attempts to
allocate CHIP memory to use PUBLIC
memory instead. (This is a very
dangerous option - don't use unless
you know what you're doing!)
Public: This option allows you to set the PUBLIC memory
emulation mode. Clicking the gadget (or Holding the
right Amiga-Key and pressing P) will toggle between
the following :
FAST: Sets VMem to cause all attempts to
allocate PUBLIC memory to use FAST
memory. (This is a dangerous option-
don't use it unless you know what
you're doing.)
CHIP: Sets VMem to cause all attempts to
allocate PUBLIC memory to use CHIP
memory instead. (You probably
shouldn't use this!)
PUBLIC: Sets VMem to cause all attempts to
allocate PUBLIC memory to use PUBLIC
memory. (This is the normal mode,and
should probably be left alone.)
Clear: This gadget allows you to disable programs' requests
for CLEAR memory. (You should probably keep this
option at "CLEAR" ).
Reverse: This is option allows you to disable programs'
requests for REVERSE memory. (You should probably
keep this option at "REVERSE").
Force: This option allows you to force programs to allocate
CLEAR or REVERSE memory even if they didn't ask for
it. (You should probably leave this at "No Force".)
(Programmers may find the "Clear" option handy for
debugging, but remember to leave it off to test your
program properly).
LowMemLimit: This option allows you to set the minimum amount of
(real) memory to keep free. This should probably be
kept at about 50000 to allow the Amiga to display
messages,etc.
Select: This gadget will bring up a "Drawer Requester" with
which you can select the drawer where you want VMem
to store it's temporary files. The more this drawer
can hold,the more Virtual Memory you will have.
Save: Sets and Saves your current preferences, and quits.
Use: Just Sets (doesn't save) current preferences, and
quits.
Cancel: Resets preferences to previous settings, and quits.
