| Don't worry. Available memory in the range of 750K is normal for hard
drive systems with 2 partitions. As you noted, the buffers for each
partition take up a sizeble chunck of memory by themselves.
Memory is consumed by the system at boot time by many different
processes. First are the buffers for all disk drives and partitions.
You will find that at the start of your startup-sequence file, there is
an AddBuffers command that will reserve memory for df0:. This value
should be fairly small. You will also notice that in the startupII
file, certain AmigaDos commands are made "Resident" in memory. You
might want to check to be sure that they are removing these commands
from memory if you really or concerned about total memory availible.
Probably the biggest user of memory is Intuition which is basically the
WorkBench and its activities. The bit-plane that the WorkBench screen
is displayed on takes a good chunk, plus any object that is displayed
on that screen will take up some more, the size depending on the size
of the object (each disk drive and partition will display a disk
object). Also, each time a window is opened, more memory is needed to
display the icons in the window. The larger the window and the greater
the number of icons, the greater the memory usage.
A machine as sophisticated as the Amiga needs plenty of memory to
operate. We're not talking Apple II or C-64 here. The Amiga is a
full-blown multi-tasking computer system. I think the dealer that sold
you the 2000HD did you a disservice only putting 1 meg of memory in a
hard drive system. 1 meg is considered minimum now in just a
bare-bones 500. Adding a hard drive and especially a hard drive with 2
partitions, is going to suck up enough memory that some programs won't
run efficiently.
My suggestion is to go back to the dealer and see if you can make a
deal on another meg. I have a 500 with an A590 hard drive and just
upped mine to 3 meg.

| Avoid the pretty hacks also.I come from a line of A1000 deprived
systems.Back when you only had 512k.To this day(3meg)I find myself
avoiding programs that give eight color workbench screens etc.I
do use virusx in my startup sequence however.Also in response to
removing the resident commands,if you use some commands frequently
you may want to leave them resident so they do not have to be loaded
in by each calling program.I am not sure if you can add a meg to
the 2500hd controller card or not.Some controllers like the GVP
offer you the option of 2meg expansion.(never realized why until
now)You may have to buy a ram expansion card for the 2500.At any
rate they come 0k,and go upward in 2meg increments.I do not think
you can add one meg at a time.My eight meg card from cbm will only
allow 2 meg increments,and the last 4meg has to be put in all at
once,I believe.
