After Dr. Hoiby's Windows Explorer 256 color TrayIcons Patch and Wijono's hot removal of USB device SYSTRAY.EXE (4.10.0.2224) Patch, both already included in NUSB, I now offer you:

dencorso's USB FDD DiskTSD.VxD 4.90.0.3000 Patch, that allows NUSB to work with FDDs without a BSOD!

Do you remember this post by Petr? [Petr, where are you??? ]


Well, it set me thinking... My first though was: how so? Win 98SE will not allow one to rename and substitue a file in use! But I tested, and in fact Win 98SE does allow it, at least in this case: it works as Petr described.
The downside of Petr's solution is that if one forgets to exchange back the DiskTSD.VxDs before shutdown, or has a system crash, the system will refuse to boot due to the failed dynamic loading of v. 4.90.0.3000! And it'll be necessary to boot in DOS to do the renaming, before the system is able to boot up normally again. So, a way to have v. 4.90.0.3000 undergo successfully the dynamic load was a must that simply had to be found... ...and here is it:

1) Fetch DiskTSD.VxD v. 4.90.0.3000 from inside your Win ME installation CD (it is in WIN_20.CAB), and extract it to a new folder named, say, PATCH.
2) Rename DiskTSD.VxD to DiskTSD.PAT and extract yet another copy of DiskTSD.VxD from WIN_20.CAB, so that now you have two identical files in the PATCH folder, differing only in the name extension.
3) Open DiskTSD.PAT with your favourite HexEditor and search for the hexadecimal sequence 00005A04, which you should find only two times, in two different places (at offsets 140 and 866).
4) Change, in both places hexadecimal 5A for 0A, and save the file.
5) Now, in a DOS box, set to the PATCH directory, run <fc DiskTSD.VxD DiskTSD.PAT /b> You should see this:
00000142: 5A 0A
00000868: 5A 0A
6) If you saw that, copy DiskTSD.PAT to %windir%\SYSTEM\IOSUBSYS, rename the DiskTSD.VxD found there to DiskTSD.ORI and then rename DiskTSD.PAT to DiskTSD.VxD. As Petr found out, you can do that with windows running.
7) If you are using NUSB24 or earlier, that's all. But if you are using NUSB31, now you must got to %windir%\INF, save a copy of USBSTOR.INF as USBSTOR.ORI, and then open USBSTOR.INF in, say, WordPad and uncomment (delete the leading semicolon) all lines referring USB FDDs (there are 8 such entries: one each for Mitsumi, HP, NEC, SMSC, Sony and TEAC, and two for YEData), and save USBSTOR.INF.
8) It's not mandatory, but at this point a recommend you to reboot your system.
It's done! Enjoy using USB Floppy Drives in Win 98SE!

Of course, the standard disclaimer applies: It works great for me, but YMMV and I can guarantee nothing whatsoever about this patch, and about the use you make of it. By deciding to use it you fully accept that anything you do is of YOUR SOLE RESPONSIBILITY... Also, to use Win ME files you must have a Win ME licence. Moreover, modding files voids the EULA, of course. You have been warned. Hence, if after performing this mod your pc morphs into a purple mushroom and explodes, causing a 10-day worldwide blackout in the process, you know you can't blame me for it!

Hmmm .....

@dencorso:

Essentially, you're changing the version checks to 4.10 to allow it to load .... something like DOS did back then ...

That has given me an idea ..... perhaps these device loaders can be used to patch older win95 too with this method. I'll try these on win98 FE to verify if these can work ... well, as soon as I can find some time ...

If it works then we need to figure a way to tag the original version numbers somewhere else ...

Rgds

Precisely so! At DDK_Version and at SDK_Version. But, in DOS, a guest program asked the OS for its version, while, in Win, AFAIK, the guest program informs the OS which Win version it was meant for. But, at the end of the day, it has the same result.
Go for it! I do believe it may work im many cases. As it was back then, programmers still today have the habit of implementing unnecessarily over-restrictive version checking.
No, we don't. The version numbers are unchanged in the VS_FIXEDFILEINFO Structure. That should be enough, don't you agree? It's us that need to know which file is which. Windows must not, or it won't work!
Best wishes.

Hmmm .....

I've made preliminary test runs of the version patched DISKTSD.VXD on windows 98 FE (thanks for the tip dencorso!) and so far has found no signs of trouble ... Haven't had the chance to tryout the usb fdd support yet ... will give an update when that's done ...

Native Usb 2.0 does not seem to work on windows 98 FE ... It seems that MS usbhub20.sys is not loaded by ntkern ... Can anyone help determine if this is also due to version checks or hardware related problem ? I'm much rusty on this thing ... any help or hints is appreciated ...

However, replacing with vendor usb 2.0 hub driver then the whole thing works. Tests was done on a VIA 8235 based usb2.0 ... So, for VIA based usb 2.0, only the usbhub20.sys file needs replacing to make it work ... I'm also experimenting with other drivers to see if there's any other possible solution ... I've also made the usb power/bandwidth property tab works but I think most users won't be too concerned (and probably will be left out later) ... I've made minor changes to the driver set to support VIA usb 2.0 ... This makes it sorta not so native ms usb driver ...

For the time being, I'm not updating the win98 FE usb driver set until I can figure out if the the above issues can be resolved.

Update:
I was looking at VIA usbhub20.sys file and wondering if it could be a generic hub stack (perhaps it is a reference to MS usb hub driver somewhere) ..... I'm curious to know why it can interact smoothly with the other "parallel" usbport and usbehci driver from MS ... Usually this kind of thing will go "huh?" in windows ...

Final edit:
Yep, the VIA usbhub20.sys seems to be based on MS DDK library ... if anyone willing to "experiment" usb2.0 on win98 FE with this please let me know ... I'll make a patch for you to tryout ...

Well, PassingBy, MS usbhub20.sys is a WDM driver (hence a PE executable), so it's a totally different animal than a VxD... By looking into it with eXeScope, you'll find out it asks for win 4.0 (= win 95) everywhere, so I think version checks are not the problem. But if VIA usbhub20.sys works, you should compare both usbhub20.sys's with eXeScope, MiTeC EXE Explorer, and PEDUMP.EXE by Matt Pietrek, to see what you find. A quick look with dependency walker shows them to have the same dependencies, which is good for a start. Good luck! Do keep us posted on your progresses. And... Keep on the great work!

Czech build Maxim Decimus NUSB v. 3.2 (only for czech version Windows 98 SE)
http://www.winpack.org/download.php?soubor=26

thx Maxim Decimus!

Hmmm .....

Thank you dencorso for your hints but I figured that one out earlier while doing some reading up and digging around for clues ...

I am pleased to report that the native ms usbhub20.sys driver is now working with windows 98 FE .....

I was snooping into via usb2.0 hub driver headers and after comparing with ms usb2.0 hub driver, I concluded that they're were both from the same base reference material (plus minus bug fixes etc etc). My guess was confirmed later on when I verified that all function calls are the same except WMI calls ... so that's where the difference is and its enough to break it ...

I'm planning to update nusb for windows 98 FE soon ..... the planned changes will be :

1. Using UMSS.SYS compiled from MS sample reference driver. I concluded that usbstor.sys will not work on W98FE due to different function calls to ntoskrnl (available only from W98SE upwards). The working replacement was found at http://sweetlow.at.tut.by/download/umss.zip

2. Minor changes to get MS usbhub20.sys loaded correctly on win98 FE ...

3. Updated explorer.exe to match nusb3.2

4. Updated DISKTSD.VXD (4.90.3000) for possible usb fdd support ?

5. Generic W98FE driver support for usb fdd. There's many drivers flying around but I believe there's a generic version that will work on nec and mitsumi drives. This is still unverified as I'm waiting to get my hands on a usb fdd to tryout.

6. Please comment if I should include the ATI usb2 fix (to match nusb3.2) ...


I'll be putting the update on hold until I can verify usb fdd can properly work ...

Maximus, you rock man! And lots of thanks to Dencorso too!
(by the way, nice idea the little flag Philco. I might just do the same some day...)

Way to go, PassingBy!

regarding your questions:
4 and 5. The patched DISKTSD.VXD (4.90.3000) ought to work OK in Win 98FE. I think no other driver will be required, besides the NUSB files and DISKTSD.VXD. If not, consider, as the first step, adding CDVSD.VXD 4.90.0.3003, previously patched by the same method to change version. I know it works OK in Win 98SE. I'm using both right now.

6. I think so, yes.

Keep on the great work!

Where do I find these two files? I want to find the Danish version of the files.
advpack.dll 4.72.3612.1700
explorer.exe 4.72.3612.1700

You'll find them in the .CABs inside the Danish version of MSIE401SP2.EXE, possibly also inside older versions of Internet Explorer 4.
advpack.dll 4.72.3612.1700 is inside ACTSETUP.CAB
explorer.exe 4.72.3612.1700 is inside IE4SHL95.CAB or, if you want the NT version, inside IE4SHLNT.CAB
BTW, you'll also find the same version of explorer.exe in all versions of Internet Explorer 5, up to IE55SP2.EXE,
but, then, the version of advpack.dll to be found will be higher than the one you asked.

Could someone repost the English package to a decent host that I can actually download from? I've had enough posting and reposting that that stupid RapidShare has something that always tells me I'm already downloading from my IP although I'm NOT.
Thank you.

Nevermind, I had a friend download it for me. Thanks anyway.

(later edit) Thank you for the link below.

I love this patch!

My portable 320GB USB2 hard disk was detected without a hitch


For those interested, I had to use the freeware SwissKnife 3.22 to format the drive from NTFS (how it arrived) to a single FAT32 partition.
http://www.download.com/CompuApps-SwissKni...8-10070864.html

Not sure if I could have done that under Win98. I did it under WinXP.
Note: WinXp's built in Format facility will not allow FAT32 partitions bigger than 32GB.

Hi, maximus-decim!
While poring over an .INF provided by Mitsumi for their USB FDD, I believe I found another brand of USB FDD that is not yet included in NUSB: the "EKE USB Floppy", which has VID_049f&PID_0054. The .INF file in question is attached for you to check whether I'm right or not, since you're much more knowledgeable about .INFs than myself. NUSB rules! Keep on the great work!
