Patched IO.SYS for 9x/ME

**jds** · January 27, 2012

Thanks for the reply jds, but i guess I wasn't clear. I meant CD and DVD drives, not a combo drive. Any disc (CD or DVD) tends to show up twice in Windows Explorer for some reason.

I was researching a problem with Vista, the opposite to this, wherein the CD/DVD drive disappears ... and I came across a KB which describes your particular problem. Of course, now that I want to reference it, I can't find it. Anyway, from what I remember, it said to boot in "safe mode" and delete the invalid entries in device manager. It described how to determine which entries were invalid and which to keep (probably by looking for "this device is operating correctly" status text, but I'm not certain). Hope that's of some help. If I find that KB again, I'll come back here and edit this posting.

Joe.

Is it possible to make the patch for Win ME, too? Till now I've hidden phantom drives.
I have updated my PATCHPAR Program to Patch the Unpacked Windows ME IO.SYS as well. You will need to get the Unpacker from my Website.
Let me know if it solves your problem.

Hi Mr. Loew.

Well, I decided to give this a try on my home PC and unfortunately, ran into a problem.

My drive H: (in DOS 7.1, without loading the W98SE GUI) produced the following from a DIR command :


 Volume in drive H is \é)ÞŠ†¥pÊ
 Directory of H:\

y‹³æ"bx 2Àí 3,273,781,586  06/04/89  11:37
         1 file(s)  3,273,781,586 bytes
         0 dir(s)          446.52 MB free

By contrast, your earlier partial patch together with my favourite two byte patches to IO.SYS produces the following :


 Volume in drive H is 2-3-FLAKEY 
 Volume Serial Number is 07EA-4466
 Directory of H:\

MUSIC          <DIR>        14/01/10   0:43
VIDEO          <DIR>        14/01/10   1:21
TH99           <DIR>        01/02/10   0:41
CDDA           <DIR>        31/03/10  23:03
FTP            <DIR>        17/12/10  20:06
CAMERA         <DIR>        31/05/11  20:56
TEMPOR~1       <DIR>        01/06/11  23:26
         0 file(s)              0 bytes
         7 dir(s)          361.72 MB free

The physical drive in question has the following partition table entries :


06 FAT16 (Primary)
E7 RS (Primary)
0F Extended Partition (LBA)
83 EXT2 (Primary)

The extended partition has a single volume (logical drive H:) :
0B FAT32 (LBA by virtue of the extended partition type)

All other drives and volumes work OK with either set of patches.

Joe.

I have not been able to replicate this problem.

What is the layout of the first Drive?

Run the attached program from DOS 7.1 and post the result.

Partition numbers 1-4 are primary, 5+ are logical volumes in an extended partition.

Everything looks normal. H: should have worked properly.

Were you running my Patched IO.SYS when you ran PARTSX or the working version?

Either way, switch to the other one and rerun PARTSX.

I believe the following combination of Partitions caused the problem

1. On Drive #1 you have a Type 5 Extended Partition.

2. The last Logical Partition in this Extended Partition is Non-DOS.

3. On Drive #2 you have a Type 0xF Extended Partition.

4. The Logical Partition in this Extended Partition is DOS.

It is a rather improbable combination but I have revised my Patch so it should cover it.

Try the attached Patch on an Unpatched copy of IO.SYS and boot with the Patched IO.SYS

Test all of your Partitions and run PARTSX again.

EDIT: This Patch has been revised and has been tested.

IMPORTANT: Four copies were downloaded before 7:15 PM EST. Do not use these copies are they do not cover all cases.

REEDIT: The Patch did not correctly handle Windows ME and has been removed. A new Patch will be posted shortly. Patches to IOSYS 7 are fine.

I see no one listens. Four people downloaded the experimental PATCHPAR I posted earlier.

I said not to download it before it was verified. I have already redone it.

@jds: If you already downloaded it, redownload the newer copy in my previous post and use it instead.

Jumping the gun a bit, but it should be OK as long as you weren't one of the four who downloaded it before 7:15 PM EST

I am removing the previous versions from the Forum as they do not cover all possible configurations of Partitions.

I see no one listens. Four people downloaded the experimental PATCHPAR I posted earlier.
I said not to download it before it was verified. I have already redone it.
@jds: If you already downloaded it, redownload the newer copy in my previous post and use it instead.

Well, Mr Loew,
I've just downloaded and this one works properly for me.

Hi, Joe!

I'm glad the latest installment of RLoew's patch worked OK for you.

But, just for completeness, would you please post the output of partsx while using it?

Thanks in advance!
