Andreas,
VRAMDIR seems to be another QP2 Virtual-like program. I use Win98
and am having trouble with QP2 Virtual. Since Windows 98's memory
structure/routines are slightly different from Win95, there might be problems
with VRAMDIR. In general, I don't like to have TSR's loaded.
They always complicate things, take resources, and sometimes cause crashes.
MEMTURBO is a good example.

and others,perhaps
you want to have a look at a tool called "vramdir" for win95. vramdir maps
one or more directories onyour hard-disk,
i.e. it does not create a new virtual drive.Vramdir
copies the directory-tree into the ram while booting and saves the tree
during the shutdown. Interestingly,vramdir
doesn't assign a fixed memory portion to the ram-disk, but increases and
decreases the amount used.When
running out of memory, vramdir starts swapping to the hard-disk. Of course,
when your computer crashes,all
changes are lost (surprise, surprise ... :-)Maybe
vramdir can speed things without needing to play with the registry.Andreas

Mario,
I thought about the RAM disk option. When I was going to the
university, I used the DOS RAM disk to compile my programs because the
computer was so slow. However, it would be difficult to use a RAM
disk in Windows 9x. Stock database programs, such as QP2, expect
to see its database in a certain drive/partition and folder. Even
if you were to figure out which files to copy to RAM disk, you still would
have to modify the QP2 Registry settings. Perhaps you could use the
QP2 configuration program and move the database to the RAM disk.
You would have to wait for your HDD to copy over 200 MB's to RAM disk.
Also, if you create a RAM disk, you probably also have to assign it a drive
letter. That means you would have to modify your Registry and numerous
other files so that, at minimum, your CD-ROM driver letter increases by
one. Because I use PartitionMagic, I have already gone through this
process several times and it is never simple.
Even something as simple as moving an application's folder to another
partition can be time consuming. There have been many times when
I was forced to use Norton Utilities Disk Editor (DOS) to modify the app's
configuration files. This usually involved changing every instance
of the drive letter in each file.

3. If you want to
do the absolute fastest stock database searches you possibly can,
then there is only 1 hard drive solution for you: SCSI/UW2.
Buy a motherboard with it built in. The SuperMicroP6SBU
at $320 would be a good choice. For a SCSI/UW2 hard drive, expect
to pay at least $340 USD for an IBM
9.1GB U2W at 7200
RPM and $600 for 10K
RPM. If you cannot afford the premium, buy the new $330 Western
Digital 18GB UATA/66 at 66MB/sec and 7200 RPM and a 66MB capable motherboard.
COMPUSA had this HD on sale for $270 with some other free hardware.
The best BX chipset based motherboard is the ABIT
BX6 2.0. It should also be 66MB/sec HDD capable.
That's a very well documented e-mail Daniel :->
Now, when it comes to the fastest database searches someone may consider
to copy the database in a Virtual RAM Disk...
A couple of things to keep in mind:
- You have to consider that it takes a while to initially copy the full
database to the RAM disk, but assuming you are making more than one consecutive
search, it is worth the initial setup time.
- Of course, you need plenty of memory or a small database....
- If your database is too large for your physical memory, you may consider
an interesting alternative: VRamDir.

As your needs will vary I suggest to simply experiment
and see by yourself.
I understand that this is not an universal solution, but some may found
that trick practical and applicable to their needs.
