Guide
friends , I've installed 1 GB DDR 333 RAM to practice SAP .

I need your help .

although 1 GB is working fine with win 2000 ,

I had to limit it to 216 MB for win 98 SE .

Now my dos applications are not running

in win 98 SE . I searched MS knowledge base &

thru Google , ... etc tried changing maxfilecache .

it is of no use .

I 've checked all known system internals .

working around this problem since 6 th Jan .

NAV reporting low memory or low system resources &

" out of memory " message appears when I

try dos command/application .

I have tried Vcache tips , increasing conventional

memory tips ... etc . sofar unable to solve it .

And the technical assistance at my system's dealer

is not up to the mark . Although it is a authorized

zenith show room !

if you have been working on win 98 SE

with > 256 MB RAM ( ex . 512 MB / 768 MB

/ 1 GB ) please mail me a copy of your

system.ini file to analyze & solve

my problem .

my mail : REMOVED ON USER REQUEST

related important settings

from my system.ini file are :

[386Enh]

ConservativeSwapfileUsage=1

LocalLoadHigh=1

MaxPhysPage=D1FF

[vcache]

ChunkSize=512

MinFileCache=8192

MaxFileCache=524288

thanks in advance
 
I have 1GB ram and Win98SE running off a USB external drive. The changes I made in system.ini for 1GB ram were....

[vcache]
MinFileCache=65536
MaxFileCache=65536
ChunkSize=512
 
seshu, here's the solution, taken from microsoft

CAUSE

The Windows 32-bit protected-mode cache driver (Vcache) determines the maximum cache size based on the amount of RAM that is present when Windows starts. Vcache then reserves enough memory addresses to permit it to access a cache of the maximum size so that it can increase the cache to that size if needed. These addresses are allocated in a range of virtual addresses from 0xC0000000 through 0xFFFFFFFF (3 to 4 gigabytes) known as the system arena.

On computers with large amounts of RAM, the maximum cache size can be large enough that Vcache consumes all of the addresses in the system arena, leaving no virtual memory addresses available for other functions such as opening an MS-DOS prompt (creating a new virtual machine).

WORKAROUND

To work around this problem, use one of the following methods:

  • Use the MaxFileCache setting in the System.ini file to reduce the maximum amount of memory that Vcache uses to 512 megabytes (524,288 KB) or less. For additional information about how to use the MaxFileCache setting, click the article number below to view the article in the Microsoft Knowledge Base:

  • Use the System Configuration utility to limit the amount of memory that Windows uses to 512 megabytes (MB) or less.For additional information about how to use the System Configuration utility, click the article number below to view the article in the Microsoft Knowledge Base:

First of all , I would like to thank you all
who have taken interest in my trouble .
I will work on your suggestions and report
back . thanks once again .
 
Well the easiest way to use win98 in modern systems is thru an emulator if you MUST use it for some purpose. Get Virtual PC 2004/VMWare/Bochs and run it thru that. No use installing win98 natively on a modern pc. Either have xp or 2k.
 
further I need your help for the following :

1 . earlier I had Hard Disk Drives Names , model numbers
in Device Manager . And I was able to use DMA for all
the drives . Now the details are disappeared and DMA
option is invisible . How can I solve this ?

2. when I rightclick my drives it takes much longer time
to display the menu . this is not so for the folders and
the files . How to solve it ?

* thanking one and all

I came across a situation where I needed to have Win98 .... I want to flash a RCP1 firmware on my LiteON 16P9S DVD ROM drive and it seems that it can only be done with Win98 - I got this info from a LiteON forum. I tried flashing in XP and it was not possible.

I would appreciate it if anyone can give me info of a way to flash a firmware on this drive from within XP.

Because I am not going to be flashing this drives firmwares often I have installed Win98SE on a 850mb 2.5" drive as an external USB - the vcache settings I gave above works fine for my system with 1GB ram.
 
I would like to add the following Query
as I am unable to edit my above post :

What is the purpose of EMMExclude setting
in the Advanced settings of MSCONFIG ?
- thanks

attachment is from windows help by
using ? at the setting option .
I didnt understand it !

I am relieved of few problems by using
EMMExclude = A000-FFFF although
I didnt understand it .
Now many of my Dos Applications have
enough memory to run and NAV is also
functioning ( as usual I believe )

I would request your advice on
DMA setting for the drives .
now , this option is completely
invisible in my system .
And right click menu on drives
is delayed . it is not so for the
folders & the files .

thanking you
 
1. As for your first query, you have limited your memory to 512, so all the upper half of memory addresses are unavaliable to the system,

EMM Exclude A000-FFFF:

This setting prevents Windows from trying to scan for unused memory address space. This also disables the Random Access Memory (RAM) and ROM search instructions for the memory address space. This scanning can interfere with some devices that use the same memory addresses. This sets "EMMExclude=a000-ffff" in the System.ini file. This is equivalent to starting Windows with the command-line switch "/d:x".

2. DMA : Win98 by default enables dma for hard disk if the disk supports it.

For optical drives, Click Start, point to Settings, click Control Panel, and then double-click System, on Device Manager tab - CDROM - Settings tab, click to select the DMA check box & reboot, if your odd gives trouble after enabling dma then disable dma again & reboot.

3. why dont you upgrade to win xp :(
 
many thanks dipdude , for your kind help .
I want to run my dos applications ,
work with tc++ ... etc without
any troubles .
I have little experience with win xp
And I am unable to get it installed
in my system . I cant afford buying
the original os .

thanks once again .

Eazy, which tool have you used, did you try MtkWinFlash or safest way is to use Mtkflash, in true DOS.

I got the RPC1 firmware from The Code Guys and used LtnRPC.exe for flashing the firmware.
 
^ eazy give the Ltnfw a go, follow the instructions carefully, should work from within xp, never personally tried it so cant vouch for it.

do backup your old firmware before flashing, also keep mktflash/floppy, in hand.

Thanks for the info - but I dont need to flash another firmware to the LiteON drive. I flashed once only to make the drive RPC1 and thats done now. :cheers:
