Re: RAM Disk or RAM-based Explorations

You still need more physical RAM to use a RAM disk scheme.  I don't think 8 MB's is enough.  If you want to use the Ramdrive.sys file, you can specify up to 32 MB's but you must have the physical memory for this.  The reason why you didn't notice any increase in speed is because 8 MB's of Metastock files will hardly make a noticeable difference. I used RAMDRIVE.SYS a long time ago in DOS.  In a computer programming class, when I was compiling a program, it took 20 minutes on a floppy.  When I used the RAM disk, it took 30 seconds.  The problem with a RAM disk is that it creates a drive letter.  This may change some of the drive letters on your system.  Since I have never used a RAM disk in Win9x, I can only guess that it would increase your CD-ROM drive letter and use the original CD-ROM drive letter.  However, since this is a (possibly 16-bit) DOS driver, I don't know what the exact effects are when using a Windows program with it. I think it would be easier just to use the Win9x cache and crank it up to whatever maximum it is.  There is a new version of CacheMan at 3.8. http://www.outertech.com/english/products/cacheman/cacheman.html It's still free.  Nevertheless, you will still need more RAM.  For example, my Quotes-Plus 2.1 database is about 384 MB's.  If I wanted to do full QP2 database searches, I would have to buy 384 MB's of memory for these types of schemes to work.  If you couldn't increase the Win9x cache to 384 MB's, you could still buy a Win9x (32 bit) RAM disk program off the Net. If you're doing a lot of large Explorations which take 18 minutes and can afford to spend $480 on RAM, this is probably a good idea.  With a 500+ MHz processor, you would probably decrease your time to 2 minutes or LESS!  If you only do 3 or 4 Explorations a day, it's not worth it.

However, I tried it quite a while ago, and some details might fall through the cracks (of my memory). This is what I unearthed in my old C:\config.sys. As far as I remember, you need to add into C:\config.sys file the following lines to create RAM drive G: =8.192 Mb in the extended memory: DEVICE=C:\DOS\Ramdrive.sys 8192 /E LASTDRIVE=G SHELL=C:\COMMAND.COM C:\ /E:512 /P Then you copy data files you want to G: and use Metastock  treating G: as a regular disk Those more knowledgeable than me please check the above if I missed something. Possibly, it was for DOS with Win 3.11. Don't know if the same commands are valid for Win95/98. But my point was  that there was no speed increase at all! Let me know if I was wrong. Cheers, Vitaly
