5.19 RAM.DRV
P U R P O S E :
This utility is used to designate part of your ram memory to be
used as a temporary ProDOS volume. The RAM.DRV utility is
a /RAM volume driver which can be used with both the Check-
mate Technology Multiram and Applied Engineering Ramworks
cards. This RAM driver is compatible with Merlin-pro version
2.30 and higher.
HOW TO USE:
RAM.DRV is compatible with the “main memory” option of
Merlin-pro, which is recommended for use with speed up cards.
it is space efficient leaving many more free blocks on the ram
disk. However if another /RAM driver better suits your needs,
then you don’t have to use this one.
RAM.DRV is similar to other ram drivers, but was written as a
SYS program (exiting through the QUIT protocol) and thus can
be used as a startup program from the SiderFile program selec-
tor.
This /RAM driver does not use any of Apple’s standard auxiliary
64k space. This decreases the possibility of compatibility
problems when using programs which use an auxiliary memory.
There are no conflicts with double hires graphics.
The /RAM volume will be assigned to slot 3 drive 1 rather than
drive 2. This is done to avoid problems with programs that do
not handle slot 3, drive 2 devices. Ordinarily running the ram
drive programs will not re-format /RAM if certain ID bytes in-
dicate the /RAM volume is still there. This check is not always
reliable, and you can force re-format by holding down the closed
Apple key when running the ram drive programs.
The driver has a “bank lockout’ that can reserve ram banks for
other usage. This is done via the byte at $2048 (currently 0 -- it
follows two FPs to make it easy to locate) in the RAM.DRV file.
The driver will not use any ram banks numbered equal to or
below the contents of this byte.
The files RAM.DRIVE.16 and RAM.DRV.16 are compatible
drivers that can be used if (and only it) you have a an Apple IIGS
