Here's another for system performace tab
Copy and paste this to a text file and save it as something.reg and then double click it.
Then reboot and check it out.
This gives GUI 2.1MB of ram instead of 64KB on super cache setting.
Something mentioned here
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\FS Templates]
@="Max Cache"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\FS Templates\Super Cache]
@="Super Cache"
"NameCache"=hex:00,ff,00,00
"PathCache"=hex:ff,00,00,00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\FS Templates\Max Cache]

Dont forget :Registry Tip for Increasing Icon Cache

**MDGx** · April 18, 2006

Dont forget :Registry Tip for Increasing Icon Cache

Thanks for the reminder.

Similar here:

http://www.mdgx.com/newtip1.htm#THRASH

and here:

http://www.mdgx.com/newtip19.htm#AOG

Please notice that "Max Cached Icons" registry setting accepts values only up to 4096, according to this MSKB article:

http://support.microsoft.com/?id=132668

Therefore 8192 [and anything else above 4096] is invalid.

Hope this helps.

**EAT MY DUST** · April 18, 2006

Thanks for that.

This is otherwise known as Vcache ? Because I got mine at maxcache=524288

If it is set in the system.ini, should I even be using this mod ?

Vcache setting [correct value is "MaxFileCache"] is present only in system.ini, not in the registry as far as I know [example]:

[vcache]

MinFileCache=4096

MaxFileCache=8192

ChunkSize=512

More details:

http://www.mdgx.com/newtip1.htm#THRASH

Vcache stands for "Virtual Cache" which is the amount of memory allocated by Windows 9x [thru the system.ini settings above] for storing files + folders reads + writes, somehow similar to smartdrv [which works only in true/pure/native MS-DOS mode, of course].

More info:

http://www.adriansrojakpot.com/Speed_Demon...mization_01.htm

More similar resources listed here at the bottom of this topic:

http://www.mdgx.com/newtip1.htm#THRASH

The registry "max cached icons" value represents only how many file/folder icons are cached into shelliconcache before the icon cache runs out. Please see the relevant MSKB article for details:

http://support.microsoft.com/?id=132668

Hope this helps.

Wow thanks guys, im trying some of these out now!

To open My Computer in a Windows Explorer type view, simply hold down the Shift key and double-click its icon.

If you are ever in need of tons of information about your registry, you can access a huge listing of your entire registry hardware keys by entering a simple run command. Just go to Start, then Run. Type in: hwinfo /ui [Enter]

Registry entries are displayed in green
File attributes in magenta
Configuration information in brown
Error messages in red
Warnings are displayed in blue

If you would like to create a desktop shortcut that will automatically boot your system into SafeMode when clicked, here's how:

Right click an empty area of your desktop.
Select New>> Shortcut.
In the command line enter this path: C:\WINDOWS\WIN.COM /D:M
then click Next.
Choose a name for your shortcut. Click Next.
Here, you can select an icon for your new shortcut.
Click Finish.
Right click your new shortcut and select Properties.
Place a checkmark in the box labeled "MS-DOS Mode".
Uncheck the box labeled "Warn before entering MS-DOS Mode".
Click OK.

ok go into start menu while holding CTRL then go into settings, then while still holding CTRL, click TaskBar & Start menu, if done correctly there should be an additional Tab called DeskBar Options, but all options are disabled... spoooky . Yes I must be the first person to find this.

Here is a tip:

Steer clear of this software: UMBPCI, QDMA, and QCDROM.

These don't work at all on my system. UMBPCI claims to support my chipset, but regardless of the options, crashes instantly at the first LOADHIGH or DEVICEHIGH command.

QDMA fails to write to the disk. Ok, QDMA works for me without any options (the ones that are supported to speed up your system). But it actually slows down hard disk access! I've been watching QDMA software for a while (throughout its various incarnations - XDMA and UDMA) and even talked with the programmer for a while. No use at all!

IMHO:

All these tools work perfect on my Intel 440BX mobo + Pentium III CPU system.

My config.sys lines for UMBPCI.SYS use:

DOS=HIGH,UMB,AUTO
DEVICE=C:\MAX\UMBPCI.SYS /S
DEVICE=C:\MAX\HIRAM.EXE
DEVICEHIGH=C:\MAX\HIMEM.SYS /NUMHANDLES=128 /TESTMEM:OFF /Q
DEVICEHIGH=...
INSTALLHIGH=...
SHELL=...
SET PATH=...
ACCDATE=...
etc...

I can't use UDMA/QDMA/XDMA tools because my HDs are hooked up to a RAID controller.

But if I connect my HDs to the built-in mobo EIDE controller [with UDMA/UATA support], UDMA tools seem to work ok.

I also know people with other chipsets/CPUs that use those tools every day without problems.

I also use QCDROM every day in my config.sys, for native DOS CD/DVD support [MS-DOS 7.10, outside Win98 SE]. Works ok also with MS-DOS 8.0 [a.k.a. WinME].

I found out QCDROM.SYS to be the best CD/DVD device driver TSR [faster, takes less RAM], better than VIDE-CDD.SYS, which used to be my old favorite:

http://www.mdgx.com/newtip1.htm#CDROM4

Certain mobo/BIOS chipsets may or may not work because of hardware (in)compatibilites.

Please notice also that these free tools are developed + maintained by programmers in their own time, with their own limited resources, and sometimes they don't have enough time for debugging or don't have enough hardware resources/documentation to test their tools with.

But that doesn't mean we should all stay away from them.

They work as expected on a lot of hardware out there.

BTW:

Have you contacted Uwe Sieber about UMBPCI.SYS?

This is his web site:

http://www.uwe-sieber.de/umbpci_e.html

and email:

http://www.uwe-sieber.de/email.html

Complete UMBPCI.SYS guide at my site:

http://www.mdgx.com/umb.htm

Please see the "RESTRICTIONS" section:

http://www.mdgx.com/umb.htm#RES

and the "KNOWN CHIPSET PROBLEMS" section:

http://www.mdgx.com/umb.htm#CHI

and also the "EXTRA TOOLS" section:

http://www.mdgx.com/umb.htm#TOO

for details about various mobo chipsets + how to make it work with different chipsets [workarounds].

The "USAGE GUIDELINES" section may provide some tips for debugging your system when using UMBPCI:

http://www.mdgx.com/umb.htm#QUI

Current QCDROM release:

http://johnson.tmfc.net/dos/qcdrom.html

XCDROM has been discontinued, but may work better on some systems:

http://www.mdgx.com/drv.htm#CDR

Current QDMA release:

http://johnson.tmfc.net/dos/qdma.html

XDMA + UDMA(2) have been discontinued, but may work better on some systems:

http://www.mdgx.com/drv.htm#DRV

FYI:

I may be biased because the developers of UMBPCI + QDMA/XDMA/QCDROM/XCDROM are buddies of mine.

**azagahl** · June 14, 2006

I am glad these work for you. I just had a bad experience with XDMA (it corrupted my harddisk during a SCANDISK). It's more dangerous than ESDI_506.PDR IMHO. I think XDMA could sometimes issue some warnings at initialization time; it seems QDMA does even fewer checks.

Have you contacted the QDMA author?

Name:

Jack Ellis

Email Johnson Lam here:

http://johnson.tmfc.net/e_email.html

He is in contact with Jack Ellis, and can forward your email to Jack or may give you Jack's email.

Jack currently maintains + updates QDMA.SYS, QCDROM.SYS + QHIMEM.SYS.

Johnson Lam posts these updates on his web site:
