(Does anyone know why when I login, the forum's 'forum categories' disappear??!
I login, and the page is blank! No topics, no nav menu, nothing! The only way to see
ANY of the forums is to log out!)


Evidently there's something about an AMR modem that is
escaping me! I've never tried to use one before, and for the
life of me cannot get any of these to work. We have sold many
of them, and never had any complaints or returns! So, I'm
either experiencing "an aneurysm" or there's a problem with
this motherboard, or it simply just does not like these
modems.

Board is a QDI Advance 10F (Socket 370, VIA Apollo Pro 133A
chipset) and of course with an AMR/CNR slot. Board does NOT
have integrated audio or modem, but for someone reason in the
BIOS there IS an area for it! There is also an area to enable
Legacy Soundblaster audio. OS is win98. ALL drivers have
been installed for the mobo.

Modem (for what it's worth) is an Aztech 56k V.90 MR2800W.
There are jumpers on the modem to make it a "primary" or
"secondary" device depending on whether the mobo has
integrated audio or not. Of course, the jumper diagram on the
card does NOT match the jumper diagram in the manual!
However, BOTH ways were tried. SEVERAL modems were also
tried.

In the mobo's BIOS; integrated audio and modem was set to
"disable" AND "auto". The Legacy audio area was also set to
"disable" and "enable". The AMR modem was jumpered as primary
and secondary, with all combinations of the above in the
board's BIOS.

The modems are NOT recognized at boot up as stated in the
manual. It has been removed, restarted, shut down, put back
in the slot, and it still won't recognize it! The PnP area in
the mobo's BIOS has been shut off, on, off, on, etc.

"Add new hardware" does NOT see it as a PnP device OR any
other device! It is not in the device manager, nor does it
show in system info under "modems". When the modem icon in
the control panel is clicked, there is NO modem there and it
asked if you want to search for the modem manually, or if you
want windows to do it. Never found. I have to 'select device
manually' and CANNOT pick "modem", that just won't work. I
must select "other devices" then "have disk", then navigate to
the drivers folder for this process to continue onward. The
.inf file IS found, and accepted, then it asks for the win98
CD....Ok so far. Then the last hardware installation window
pops up saying the usual "windows is now ready to
install....." blah blah blah, and to click "finish". All
windows are automatically seemingly abruptly closed for some
reason, and that's it. No installation confirmation, no "do
you want to restart", nothing. Device manager still shows NO
MODEM, as does System Information still shows no modems.
Modem icon in the control panel when clicked still says "no
modem" and starts the "modem find wizard". However, the ONLY
PLACE on the ENTIRE hard drive where any modem IS mentioned is
under the SOUND CARD in the device manager! (The "Sound video
and game controller" entry). Expanding the PCI sound card's
"tree" you will find "56K Riser Voice Modem Wave Device".

I am aware of the "affiliation" between some sound cards and
modems, but that is of no help here. Properties for that
modem entry under the sound card are typical for any other
device and states "this device is working properly".

The computer is working perfectly, no errors, no crashes, etc.
Sound card is also working fine (PCI SC4000 with ALS4000
chipset).

The modem has an "audio" connector which can go to a connector
on the sound card (according to the manual) or audio chipset
on a mobo if it has integrated audio.

So, what I am I missing here? Does that connector on the
modem HAVE to be hooked up to WOM on the mobo or sound card
for it to be "installed"? If so, I've never seen this
required before. This is the only thing I have not tried (and
only because I don't have one of the cables handy. It's not
the typical audio cable with the FLAT black plastic end you
see with CDROM drives, but they type with the white plastic
end, and there is a connector for that on the modem and the
sound card. "Mitsumi Standard" Vs "Sony Standard"). The
connector on the modem is labeled "audio" and the similar
connector on the sound card is labeled only "GLGR" which is
obviously for the other type audio connector.

Is as though these modems are "dummy devices", completely
"D-E-A-D". One I could understand, but not 3 of them, and
again many have been sold with no problems.

I believe I've covered everything, :) thanks for any info.

I have the same AMR modem (bought from package2u) and its running just fine on two mobos (Asus and ECS). It is set to 'primary' when there is no built-in sound active so any references to a sound card in the BIOS should be disabled. Also try to set the COM ports under the BIOS to auto (or disable them ). There are also TWO types of these AMR modems. One version is made for Fujitsu-Siemens and one is made for Packard Bell-NEC. Check here for the drivers.

The path of action is this:

1) Plug the AMR card. (Which, essentially, is an MC97 bus slot, attaching a codec with a line interface behind it. The modem engine is in the chipset. Same arrangement as with sound.)
2) Enable the chipset's modem engine in BIOS.
3) BIOS should now probe for the attached MC97 codec, and if it finds one, leave the modem engine enabled, else disable it again.
4) You should now see a "PCI simple communication device" in your PCI device report (BIOS and/or Windows).
5) Install drivers.
6) Use.

Your report looks like failure in step 3. Note that a board's BIOS may choose to restrict the choice of codec devices to certain ones.

I've been using AMR modem cards from ECS (PCTel codec) and Epox (SmartLink codec) on various ECS boards, attaching them to many different chipsets from VIA, SiS and even to the C-Media 8738 sound chip. Works like a charm.

However if your board's BIOS refuses to enable the modem device in the chipset, then it's a lost case. (btw, that primary/secondary codec thing might also need some jumpering on the mainboard itself.)

Thanks guys. These came from CompGeeks and DID come with drivers. However, going to Aztech's site and looking at their drivers is when to my dismay I see that it appears these will only work with Packard Bell-NEC or Fujitsu-Siemens PC's. ??? Evidently not since you guys state they worked for you. The win98 drivers that Geeks packed with the modem are the Fujitsu-Siemens drivers. I tried both with the same results. I also tried the drivers @smartlink's site here and while they didn't work either (they state 'cannot open port'), they at least got closest to working....at least with them the modem DOES show in the device manager and under 'modems' in the control panel, however 'diagnostics' keeps saying "cannot open port".

I'll try your suggestions, thanks again. :)

In the BIOS there are no "COM ports", only serial ports 1 & 2, and I tried setting them both to 'disable' and 'auto'. The area for 'on board audio' and 'on board modem' was set to 'auto', 'disabled', and a combo of both for each. (Again I don't know why these areas are there since the board has no integrated audio or modem). The card is NEVER seen right after POST when you are presented with the IRQ assignments....all that is there is the usual display controller, USB, sound card (MM controller), and serial ports if they are enabled. It appears the BIOS is just not seeing the card due to that last fact. Can one of you please give me the CORRECT DEFINITIVE jumper settings for primary? What is on the card is different from what is in the manual, and FAIK both may be incorrect. Can someone please verify that PRI is NOTHING on J2 OR J3 (both OPEN), and pins 2-3 shorted for J1? This is what the manual shows, but the card states pins 2-3 shorted for ALL jumpers.

<later>, well, it's working now. In the BIOS I set the 'audio' to 'DISABLE' and 'modem' to 'auto', and had to short pins 2-3 for ALL jumpers; J1, J2 & J3. I don't have a dial-up connection I can test it with (DSL here), but it's now 'communicating' ok when I go to 'diagnostics' and 'more info'. It was recognized this time after POST, and with PnP, however it never asked for drivers! I guess they were still on the HD, and I don't know which drivers now it's using since all three types were installed!

Thanks for the help guys. :)

Don't you have to have the integrated sound option for an AMR or CNR modem to work?

The "COM port" you see from the AMR modem is _not_ related to the actual physically present COM ports. It's just that the AMR modem driver installs a software impersonation of another COM port, to enable old software that still believes modems are boxes connected to serial ports.

Bozo, evidently not. I've seen mobo's w/AMR slots that have no integrated audio, this board is one of them.

OK Didn't know for sure but it was my understanding that AMR/CNR modems use the motherboards built-in audio codec to do their stuff. I've seen boards with AMR/CNR slots without built-in audio as well but these boards also had flavors of them with the built-in audio so I assumed that rendered the riser slot dead in those versions.

Don't mix up codecs and engines. AMR/CNR modems have the codec on the card, and use the chipset integrated modem engine. Same with chipset sound - the engine is in the chipset, the codec is in an isolated spot near the connectors.

Most system chipsets run the sound and modem engines independently, so you can use the modem w/o using the sound.

Some solutions (e.g. those that use a C-Media 8738 sound/modem chip) however don't let you disable the sound engine whilst keeping the modem.
