Hi, Ron.
Thanks for your suggestions.

As it turns out, what was keeping the PC from booting was the MaxFileCache value. I was able to boot with MaxPhysPage=38000 and MaxFileCache=30000. If MaxFileCache was above 200000, the PC wouldn't boot. Below 200000, it would boot, but running an MS-DOS program would throw the error, "There is not enough memory available to run this program." The error occurred at 40000 but not at 30000.
I'm now able to boot into W98 SE and run MS-DOS programs. That's exactly what I wanted.
regards, Andy
If that's not enough, be sure to read thoroughly all that's been posted about "Win 9x/ME with more than 512MB" (and follow the links therein), including the present thread from the begining and also these others:

Thanks in advance
Here is the easiest solution to limiting memory with Win98:
1. Run [msconfig].
2. Click on the [Advanced] tab.
3. Put a "check" next to [Limit memory to].
4. Then change memory value to read [512].
5. Reboot.

The problem is...i can't get install windows98...how I modify system.ini if it was not created yet? :S

From memory windows starts to install, but on its first restart it crashes right?
So let it start to install as normal, then when it gives you the error about not enough memory to initialise...
You have to use a boot disk to get to a command prompt.
Put in a boot disk, press Ctrl-alt-delete to restart the computer
Then type EDIT
The press "Alt F" to open the file menu. Scroll down and select OPEN
Browse your file system and find system.ini in your WINDOWS folder.
Add the line:
MaxPhysPage=30000
save
Close
press ctrl-alt-delete to reboot again
Windows should continue its setup process.

MaxPhysPage=30000 has to under the [386Enh] section of SYSTEM.INI.
You will need to put MaxFileCache=65536 under the [vcache] section in SYSTEM.INI.
If there is no [vcache] section then just add it to the end of the file.
After Windows has installed, you can experiment with these values to find optimal maximums.
You can get to a 98SE command prompt by holding the Ctrl key as Windows starts.
You may need to hold the Ctrl key just after the computer beeps after the POST.
The Microsoft Windows 98 Startup Menu will appear. Select Safe mode command prompt only.
This can also be used when you are testing values of the above and Windows does not start.
From the command prompt, type edit c:\windows\system.ini
Use the Alt key to bring up the Edit menu.

Well, the last resort is to try rloew's RAM Limitation Patch. It's not for free, though. But the demo is, so you can test and see whether it solves your problem. HTH.

Not anyone I know of. But people elsewere reported favorably on it.

Yes, this is now also my case of troubles:
I still use Win98SE (multiboot with DOS, WXP, Linux) and I just upgraded
RAM from 1GB to 2GB (my system is 945/ICH7 mb & 7600GS PCIE 256M VGA).
I hadn't any problems under 98SE with 1G, as I know about VCACHE issue I
limited it in system.ini:
MaxFileCache=261120
MinFileCache=32768
ChunkSize=4096
...
MaxPhysPage=40000
As this works fine I didn't expected further problems with adding
more mem. I just pull two 1G DIMMs and when 1st booting 98SE it
hangs in text mode screen with blinking cursor. I tried safe mode
but got insufficent memory message during boot. When I tried normal
mode again, it went further but I got only VGA mode 640x480/16
with message "There is a problem with your display settings. The
adapter type is incorrect, or the current settings do not work
with your hardware [OK]". Then display dialog appeared. I tried
to set some higher resolution, reboot but then it hanged again.
I search a lot of topic on web and try adjusting vcache size and
lowering physpage limit, even some patched vcache.vxd but nothing
helped.
I also found Loew's memory limit patch demo. 1st problem was that I
use czech win98se so patch didn't applied. I had to seek some
torrents to get eng. ISO. I backup my system and made clean
win98se-eng installation. I needed to modify system.ini physpage
to complette installation to solve insuficent memory error.
System seemed to work OK with 2GB installed - seeing only 1GB.
But after I installed ForceWare 82.69 drivers for my nVidia
it become unbootable like my CZ version, hanging during boot.
So then I tried Loew's parch 3.2 demo. Now it successfully patched
the english files. I booted safe mode and it booted OK and
even show up all 2GB.
http://rayer.ic.cz/350d/WIN2GBPT.PNG
Well but the problem is that in safe mode VGA drivers are not
loaded so I cannot see if it will works together like in normal
mode. I don't need to use whole 2GB under 98SE (1G is enough) I
just want boot it in normal mode with display driver in usable
resolution.
I also tried to change VGA to my older 6600GT 128MB and same problem.
It seems like VGA LFB memory mapping conflicts with something else.
But I don't understand why. If I'm right, W9x use for this system area
located C0000000-FFFFFFFF. My VGA use LFB at always at D0000000-DFFFFFFF
despite I use 1GB or 2GB RAM it's in system area where it fitted well before.
Do you think that Loew's patch (full) will solve it or is there other way
to use it with limited memory?
Can be size of memory limited at very low HW level? I mean e.g. program
945 MCH chipset to temporary disable one DIMM bank to reach same
effect like when DIMM removed physically?

After some days of messing I finally found HimemX XMS manager freely available here http://japheth.de/Jemm.html
which allows you to limit XMS size by /MAX= option. After I limit XMS to 1GB it boots and seems to work fine!
Of course windows sees then only 1GB but it's acceptable for me, I don't need then any commercial patch.
Here's my lines of system.ini:
[386Enh]
MaxPhysPage=40000
[vcache]
MaxFileCache=261120
MinFileCache=32768
ChunkSize=4096

Could you write a quick step to step of how to install and use this Expanded Memory Manager
This will come in handy more and more in the future, no doubt.

Nice!
xrayer, does this also let you boot into Safe Mode?
This was always a problem with 1.5GB or more of RAM since the SYSTEM.INI memory settings are ignored in Safe Mode.
I wonder if by limiting RAM at the XMS manager level, it might be possible to get more RAM available to Windows than the current maximum 1152MB?
1280MB?
Something to look at!

Installation of himemx.exe is quite esay, just download it, extract himemx.exe to windows directory and replace the line in config.sys to calling this driver. It has regular EXE stub so you can type "himemx.exe" in command line to get help, also there is included documentation and source code

I think you should add Xeno86's fixed VCache.VxD to your system, at least because, when in Safe Mode, as you know, system.ini is ignored, so that your system is at risk of crashing from VCache getting too big. It gives you a default of 393216 (384 MB), which is much safer than 800 MB, and you still can keep your MaxFileCache=261120 entry in system.ini file, for normal mode operation.
And, finally, if you feel like it and have time to do it, I'd much appreciate to know how your system behaves when limited to 1280 MB and to 1536 MB, with a XMSDSK of 262240 and MaxFileCache=114688. Yes, these are the settings that work in my 1.5 GB system, but I use a 32 MB video board with 64 MB AGP aperture... My guess is that your system won't work with 1.5 GB but may possibly do so with 1.25 GB. Since you are the first to discover that windows 9x/ME in fact does not directly detect how much RAM the system has, but relies instead in what the XMS manager tells it, you should also be the first to explore the tweaking possibilities this knowledge opens up to all of us.
You rock!

I wrote a small patch yesterday http://www.volny.cz/...os/w98iopat.exe which fix IO.SYS to load himemx.exe instead of himem.sys for safe mode. I don't have problems with crashing in safemode (btw I know about mentioned fixed vcache.vxd). Just copy patch to root dir beside io.sys and run it (make backup before).
I didn't much experimended how can be RAM increased, I just try a few values 1.5G 1.25G (physpage=60000 resp 50000) and it hangs during boot so I gave it up, some additional few megs + are not much important for me, I need stable system. I laso tried to eat excesive RAM with XMSDSK but it didn't work for me.

Here's my win98's modify steps
1. Download HimemX from http://japheth.de/Jemm.html
2. Copy himemx.exe to win98 directory
3. Add the line in config.sys
DEVICE=C:\WIN98\HIMEMX.EXE
4. Here's my lines of system.ini:
[386Enh]
MaxPhysPage=48000
MinSPs=16
ConservativeSwapfileUsage=1
DMABufferSize=64
[vcache]
MaxFileCache=65535
ChunkSize=1024
After these step, I boot win98 with 2G RAM successful
In winXP, the sysem can detect 2GB RAM

And in win98, the system can detect 1150MB RAM

I think there might be a little problem with your IO.SYS patch!?
Look at the bytes in the following 2 lines: (o=0x0, d=0xd)
\HIMEM.SYSo/TESTMEM:ONdoo
\HIMEMX.EXEo/MAX=999999do
Since HIMEMX.EXE is one byte longer than HIMEM.SYS, the termination zero-byte 0x0 is moved one byte to the right by your patch. But this is exactly the byte where the HIMEM parameter /TESTMEM starts. So if IO.SYS is using the usual method of addressing strings (with a fixed address table), and I´m quite sure it indeed does it this way, then this address pointer for the parameter now points to this zero-byte (instead of the starting ´/´ of /MAX=...). So this parameter /MAX=999999 isn´t used at all by IO.SYS, I´m afraid!
A simple solution would be to just rename HIMEMX.EXE to HIMEM.EXE, so the length would be the same as HIMEM.SYS and the terminating zero-byte doesn´t need to be moved.
Furthermore you could now even use 1 full GB (1048576) instead of 999999, because after the /TESTMEM string there are 2 zero-bytes (but only 1 is needed of course), so you could increase the string length by 1 byte.

Good poit, can we display or log what will io.sys really call?
Anyway renaming to himem.exe is the simplest way to be sure.
Another thing is if /MAX= is needed at all, StarRiver claims
he run without this parameter. Hm, I will need to do some
more testing.
