With this in mind, let's see if I understood well : dare I ask, what you are saying amounts to Windows/VMM at startup remapping to system memory space (the 3rd virtual gigabyte) any XMS memory blocks that were allocated (in DOS presumably) before Win started ? Makes sense !

Ninho:
Thanks for the heads up. I've, now, corrected my post.
But I forgot to answer your question, so I'm doing it now:
Yes, you've got it right. That's exactly what I meant.
And XMSDSK is just a good example of a program that allocates XMS from DOS (run from autoexec.bat or from config.sys), before Windows even begins to load. There are other examples, but I think ramdisks are the most useful nowadays. I think Igor Leyko didn't cover this subject in his article because it would render even more complicated a subject that, as you yourself have said, is not easy at all. But in the present thread it is unavoidable to consider the case of ramdisks, because, IMHO, they are a must for systems having more than 1GB of RAM installed.

BTW, let me ask you one thing, please: does, perchance, "железа" mean "hardware"?

In computer parlance - yes it does. However, the prime, 'dictionary' meaning of the word is 'iron'.

[dencorso]

So, I'd guessed right!
Thanks a lot for your swift reply. You rock!

[GreyPhound]

Igor Leyko's text has been fully translated now, but the text is rather long.
For some reason, I can't find the 'attach file' option in my settings here.
I believe I had it some time ago, maybe last year ...
Should I go back to my original (part 2) post, and try to append this portion? (at the risk of making it the longest post on this forum,) or post it separately (part 1) and have people read it backwards?

[dencorso]

GreyPhound:

Awesome! You rock, you really do!

As for your questions:

1) For some reason I don't understand, the 'attach file' option has been disabled in the "Windows 95/98/98SE/ME" main forum, for as long as I can remember, although it is enabled in the "Unofficial Win98 Se Service Pack" subforum...

2) IMHO, it'll be much better if you can add part 1 to your original post, regardless of the final size of the post. After all, if you do that, every one who reads your translation, from now on, will be able to read it in order.

[GreyPhound]

Done.

Wonderful job translating the article, things are nicely explained in it. However, the original question still stands, and I seem to have the same problem, namely:
- I have Win98SE (no patches as far as I know, other than the one for large disk access) on an EPOX EP-8KRAI with an Athlon XP, with 2GB RAM in two sticks (DDR400, PC3200). Used to have 512MB, without problems up to the upgrade;
- After the customary MaxPhysPage and MaxFileCache restriction to 40000 (1GB) and 524288, windows boots nicely, no immediate apparent problems - but MS-DOS produces the "not enough memory error", no matter what I do.
- I've tried EVERYHING, nothing makes DOS work.

- AGP aperture is 64MB; tried to reduce to 32MB: no luck
- VCache down to 32768 changes nothing, below that windows starts to refuse to boot (not enough memory). The setting is applied correctly, verifiable with System Monitor.
- PhysPage as 60000 (1.5GB) does not boot at all; as 3C000, 30000 or even 20000 (back to 512MB!!!) does not help. windows boots, DOS does not work. The setting is applied correctly, verifiable on every about page and with System Monitor.

...now what? I'd rather not physically remove RAM, because I'm dual booting with XP which is fine thank you and makes good use of it. Any ideas, please...?

@Max Monroe:

Pleases try this extreme configuration:

(ii) NO XMSDSK.EXE
(iii) HIMEM.SYS /NUMHANDLES=96 /TESTMEM:ON /V

2) NO Autoexec.bat at all

3) in System.ini
(i) under [386Enh], MaxPhysPage=38000
(ii) under [VCache],
MinFileCache=0
MaxFileCache=29696 ; 29M
ChunkSize=512

>>> Note that MaxFileCache=29696 really, this is not a typo. <<<

4) AGP aperture 64MB

...and let me know what happens. Good luck!

Did you mean "DEVICE=HIMEM.SYS /NUMHANDLES=96 /TESTMEM:ON /V" ? Well, it didn't work, anyway. Win98 didn't boot, with "no memory". Had to return to 40000 / 65536. Aaaaaanyway, thanks for trying, and here's the RAM dump, perhaps it helps....

FED00000-FEDFFFFF = 100000
FEF00000-FFF7FFFF = 1080000

Which totals to 1B93FE00 => 451839 kB on doing Igor Leyko's calculation.
Subtracting a VCache of 65536 KB, the result is 386303 kB... But note that this is fragmented real memory.
And it seems not to be enough for the Ring 0 VM (all Windows VxDs) and additional DOS Boxes (DOS VMs).

I'd do a backup first and then...
I'd try to remove ACPI (and APM) from Win 98, to liberate some more memory on the 4th GB...
I've posted a how-to here (link) some time ago, for other reasons, but it might solve your problem.
Then again, this is just a wild guess...
Anyway, good luck! And please do keep me posted on it.

Hi again, GreyPhound!

I just finished reading it and found a small typo, that needs correction:

As a rule, AGP devices use addresses starting from E0000000, that is 3,5 Gb. Disk cache at that can use a half gigabyte. This is exactly what determines a recommendation to limit cache to the value of 524288 Kb (512 Mb).

This notwithstanding, you did a fantastic job! Thanks again!

-----------------------------------
XMSDSK Failure
-------------------------------------
Whenever XMSDSK succesfully creates a ram drive then my dos windows become unavailable for the "out of memory error"

MOREOVER XMSDSK does not work properly: when I start the scandisk, to check the sectors into the ramdrive Z, the write attempt fails after a while.
A more simple copy write attempts fails too.

The failure happens not at a specific point.

what happens is that I got a blue screen with not recoverable error sayng things like:

"An exception 0E has occurred at 0028:C0004D6D in VxD Vmm(01) + 00003D6D. This was called from 0028:C19359C4 in Vxd Rmm(01) + 00000254"

I have tried many different settings for XMSDSK.

Hi, vick1111!

Please try:
c:\ramdisk\xmsdsk.exe 262272 Z: /c1 /y

**yes, without the "/t", despite all you can read about it: there are reports this may solve your problem.**
It's said it works for 2GB or more RAM. I never tried it, because I've not encountered such a problem, probably because I've got only 1.5GB, I guess. Good luck!

Nope, that's copy-pasted as it came. Anyway, both are kinda "video card" stuff, so I assume it might not be entirely wrong to overlap / be dual allocated / accessed. Actually, I do kinda wonder WHAT THE HECK does the video adapter with THAT kind of memory allocated to it... It's a 128MB ATI Radeon 9600, for Pete's sake...

Thanks, but as one of the posters in the other thread noted, I'm not in a hurry to get rid of ACPI (if I understand correctly, the 3 to 4 GB area really matters, and ACPI seems to hold a lousy 20MB there), especially since disabling it in the BIOS would shoot it under my other OS (XP) too, I suppose.

As much as I hate that, I might just finally dump '98 alltogether, because I'm stuck with disturbingly-not-current versions of much everything lately, things crash a bit too often for lack of resources and so forth. It has recently come to the point of nobody giving a crap whether their app runs on 98 or not (mostly not), and I'm NOT willing to get stuck in the stone age of software if only that keeps working. Not being able to watch a current MOV clip on the net just about does it...

Note that my how-to was written with other purposes in mind. For a double boot machine, I'd recommend to skip the BIOS part, so as to leave ACPI for the other OSes. And, then, remove ACPI from Win 98 only (this causes Win 98 to switch to APM). And the remove APM also from Win 98 only. As well as disable NVRAM/ESCD updates and IRQ Steering in Win 98 only. It can be done and works OK. What remains to be seen is whether this also can solve your memory problem.

Does the WinME virtual memory manager work with Win98SE?

If so, I think this would be the only way to get 2 GB working, otherwise the most is a little more than 1.5 GB.

My oh my, someone is in a cranky mood today... We certainly can go back to the Spectrum, the punched tape, or Babbage if you wish, but let's not, shall we? I arbitrarily define as stone age version any software that does not enable me to use features considered standard these days, features that my hardware would otherwise be quite capable to perform. And most software today is a GENERATION beyond their last version that supported win98, usually more than fulfilling the criteria above. I could even live with that, I suppose. But when a properly set-up memory upgrade wrecks the runnability of a quarter of my programs, plays tricks with the audio with the rest, and the best advice I get is to shoot the ACPI too to solve all this, I start having second thoughts, pardon me.

So.

You say all this isn't very constructive? Excellent observation. Perhabs you have an idea then why is a 128MB Radeon allocating 512MB of virtual address space, given that most people's video adapters take a QUARTER of that...?

...Thought so. Thank you.
