Upper Lower Filters in XP Registry

[Neal Lavon]

Jim, I also just saw a BIOS update for the motherboard that says:

Fix HDD in master may not be detected while CD-ROM connects to slave.

Grrr.

Jim, I just changed not only my configuration but used two CD-ROM
drives with nothing, although there was some progress. I did re-cable
the CD-ROM as a slave using the top IDE connector of a new ribbon
cable. The DVD-ROM drive is now below it in the computer case. When I
first booted up with the Liteon, nothing.

I replaced the Liteon with another ATAPI CD-ROM I have and when that
booted up, I noticed that the little icon for a spinning CD appeared
briefly by the mouse and seemed to "want" to load but in the end, did
not. I still got the same error message in Event Viewer.

For what it's worth, here's the data in the box below the error
message:

There is no trace of Nero software (Ahead Company) (InCD left) in
Add/Remove Programs. So I'm really stumped and frustrated.

Questions:

a) someone in a thread here said that the PxHelp20 PFC file is
corrupted. I have seen that it's a Trojan Virus and keeps CD-ROMs from
working properly. It is in the Drivers file. How does one "disable"
it? Just remove it from the Drivers File?

b) delete in the Registry the Upper and Lower Filters.Bak files? Run
cdgone.reg again?

I think I'm nearing a possible solution here. Thanks!

Hi Neal - If you've wired and jumpered as you say, then you may well have a
conflict. I'd just switch the middle and end connectors (moving the drives
if needed for convenience) if your documentation recommends that the one you
currently have jumpered as Slave should be that way - some drives cannot
support being a master. For right now see if that fixes things for you.
[Later you might want to do some reading on the net about alternative
configurations such as having each HD be master and each CD/DVD drive be
slave. Do a Google on this for more info - it's thought by some experts to
have some advantages. Let's see if re-connecting the drives cleans things
up first though. Then you can look at things like that and doing such
things as enabling DMA for your CD/DVD drives (which is a whole other thing
) ] Please let us know what happens.

Hi Neal - You need to also check on the individual drives to see how the dip
switches or jumpers are set and be sure that they correspond with the places
you've placed them on the cable. That is, the DVD (which I now understand
you've placed on the middle connector) needs to be set to Master or M or
however it's marked, while the CD-ROM wants to be set to Slave or S, or
whatever.

Hi Neal - I'd leave this alone for now - you're not AFAIK showing that
symptom at the moment. Upgrading firmware for a BIOS can be a little tricky
and has to be done "just right", EXACTLY following EVERY STEP of the
directions, or you risk making your machine unusable. After you get things
cleaned up, you can make that update - download it and read the directions
VERY carefully, several times, and don't proceed until you're absolutely
sure about what you need to do (and you can also check for any possible
updates to the firmware for those two optical drives.)

I did check on the CD-ROM drive and the DVD drive. The DVD is set as
Master and is in the middle position on the chain; the CD-ROM is set
as slave and is in the top position. Both are put on my motherboard,
an Asus PG51d, to the Secondary IDE channel.

The board has RAID as a possible configuration although the secondary
channel defaults to IDE unless RAID is enabled. I'll check that in
BIOS setup. Any idea on the continuing 51 and 11 errors? I did get a
new IDE cable--blue connector to motherboard, middle connector to
DVD-ROM, top connector to CD-ROM. I really thought that was going to
do it.

By the way, Asus has a nice Windows environment BIOS flasher utility
which I've used before and worked well. Thanks again for all the
interest in this.

Just another thought, Jim. I got off the phone with Asus Technical
support who said to put the optical drives on the primary IDE connector
on the motherboard and the hard drives on the secondary IDE. Does that
make sense to you?m What do you think?

[Jim Byrd]

Hi Neal - Well, I'm not clear on just why, but it could relate to a
peculiarity of how that particular MB handles those channels and/or how the
OS enumerates them. (It occurs to me that this might be a Plug'nPlay issue,
also. You might want to disable that service and then try deleting and
reinstalling the optical drives one at a time using the original install
media that came with them. Restart PnP after you finish) I don't see any
obvious reason why it would hurt, so why not? Neal, I'm going to be leaving
this thread (I'm going in for some fairly major 'body work' and will be
out of these newsgroups for a while), but I've asked some of my fellow MVP's
to take a look at this thread and see if they can offer any assistance to
you (may be better anyway, since I haven't done you much good ) Good
luck with this!

I understand, Jim, and I appreciate all the time you've given this.
I'll just post to this thread when I reattach the drives to different
channels on the motherboard.

Good luck.

Upper and Lower filters ARE GREAT

Ive probable done this hundreds of times to fix cd rom issues caused by software conflicts. I have yet to see removing these filters cause a system to not boot. I would say follow directions exactly and you would be fine.
