<BLOCKQUOTE>Mario, <BR>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.
<P>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.

2.0</A>. It should also be 66MB/sec HDD capable.
<BR></BLOCKQUOTE>That's a very well documented e-mail Daniel :->
<P>Now, when it comes to the fastest database searches someone may
consider to copy the database in a Virtual RAM Disk... <BR>A couple of
things to keep in mind:
<P>- 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.
<P>- Of course, you need plenty of memory or a small database....
<P>- If your database is too large for your physical memory, you may
consider an interesting alternative: VRamDir.
<BR> <A
href="http://www.users.uswest.net/~jzhong/vramdir.htm";>http://www.users.uswest.net/~jzhong/vramdir.htm</A>
<BR> As your needs will vary I suggest to simply
experiment and see by yourself.
<P>I understand that this is not an universal solution, but some may
found that trick practical and applicable to their needs.

AM<BR><B>To:</B> metastock@xxxxxxxxxxxxx<BR><B>Subject:</B> Re: Avoid problem
new PC<BR><BR></DIV></FONT>I have a small addendum to my post: <BR>If you are
using Windows NT or are planning to upgrade to 2000 and you don't mind using
Celerons, then you might want to consider buying the $150 <A
href="http://thetechzone.com/reviews/motherboards/bp6/index.htm";>ABIT BP6
motherboard</A> (MB). The BP6 is the only dual socket 370 BX chipset MB
on the market. It is also one of the few BX chipset MBs which is Ultra
ATA 66 MB/sec capable. From what I understand, the BX chipset is not 66
MB/sec capable and must be modified by the MB maker for 66 MB/sec
support. The BP6 has a second 66 MB/sec HDD 2 channel controller making
it 1 of only 2 MBs, I am aware of, which is eight (yes 8) IDE device capable.
<P>The Abit BP6 is an exceptional MB. Unfortunately, you either must use
NT or 2000 for dual processors. If you want to use it under Win98 in
single CPU mode, contact Abit to make sure the ATA-66MB/sec drivers are
compatible with Win98. I believe Pentiums will coming out next year in
the socket 370 form factor. This will allow you to run the MB in 100 Mhz
FSB mode. However, you will have to contact Intel and Abit to confirm
this. You may also have to flash your BIOS for Pentium compatibility.
<P>The other MB which is eight (yes 8) IDE drive capable is the <A
href="http://www.fps3d.com/articles/be6/";>Abit BE6</A>. The BE6 is a
single Slot-1 CPU BX chipset based board. It also has a third-party
Ultra DMA66 66 MB/sec controller on the board. This is an Abit
modification. Since Abit is a major MB manufacturer, I hope that other
MB makers will also include a second HDD 66 MB/sec controller. However,
I don't know how many IRQ's the IDE controllers use. It would be an
inconvenience if it used 4 instead of the standard 2.
