Intel's drivers work great for the 2.4 kernel, but won't work on the 2.6. I was able to connect under Red Hat 9 after compiling; now that I run Fedora Core 2, I can't.

Driver from Intel is not made for Slackware and there are problems with the driver staying after reboot. It does work though, but with some bugs.

XH1154 Modem 56K 536ep PCI Int HaM V2
Intels own driver worked perfectly and installed without a hitch with Vector Linux v.4.0 which has the 2.4.22 kernel , when I upgraded to Vector Linux 4.3 the same driver is no longer any use.It seems Intel has no interest or intention of releasing a driver for the current Kernel (2.6 at time of writing).
Very sad because Vector Linux is a killer distro and 4.3 is the first Linux that has ever successfully found and used my accursed Aureal Vortex soundcard with no extra fiddling to configure it !

Installs without a hitch... during bootup I get an error associated with the file or reference to a file relating to the ??536ep.o file.. but the module loads and works perfect... I was using 8.2 upgraded to 10.0, once I realize that the modem driver don't work.. I switched back.. I didn't even have to go online for a driver for 8.2.. one was supplied on the modem's driver CD... Intel needs to supply a driver for the 2.6* kernel and fast

Installed the driver intel-536EP-2.56.76.0.tgz for 2.6 kernels, installed ok ish, apart from not auto installing due to an unknown distro (only recognises SUSE,Redhat,Connectiva,Mandrake (maybe a few more)) after running the commands in the install file manually i got it working, only to encounter a kernel panic after about 30mins (may have been due to using a usb scanner at the same time). Not recommended for machine you depend on running 2.6 series kernel.

Here is a link to an Intel 536EP driver for linux 2.6

http://linmodems.technion.ac.il/packages/Intel/536/intel-536EP-2.56.76.0.tgz

I didn't have problems with this driver at all, there is a readme.txt in the zipped file giving the proper directions. It runs like a charm.

Installed without any problems. Works quite good. The only thing is that sometimes when an improper shutdown occurs and i try to dial after rebooting, kppp gets stuck and the keyboard seems like its disabled. Then i have to log on to windows, connect to the Internet, disconnect, and again run Linux to make things work again.

Worked once I installed driver from intel without
any problem (boot will say kernel is tainted but
that is normal).

As a newbee I observed I was always connected
at 33,000 I do not know why (I believe it is not a kppp
problem). When logged with zindoze it is 44,000 usually.

Added 07/02/05
This was resolved by tweaking the Hayes AT commands
in kppp, but only for one connection

536ep_AT_commands.ZIP
05/04/05 In fact still doing 33000 bps, no idea why.
95% of the time it is slow. Not an ISP problem
but a rate negotiation problem of some kind.

http://downloadfinder.intel.com/scripts-df/download.asp?url=/8024/eng/intel-536ep-4.69.1-mdk10.1-smp.tgz

or was it mdk10.0 intel driver (I cannot remember)

The driver installs fine - but beware anyone with the "publishers edition" of RH9 - this is incomplete and the driver will not compile - however, the modem will hang after a few seconds of operation... no known reason.

There is a suggestion that the error lives in the 536ep-boot script, something wrong with the perl script... but I gave up before learning perl.

Apparently works fine under mandrake.

I could compile and run the driver, but could not connect to the internet through /dev/536ep or send any intitialization strings to the device. Finally broke down and bought an external modem.

Hi, I'm completely new to Linux so appologies if I'm missing something increadibly simple. I'm using the driver for kernell 2.6 mentioned on this thread, I've extracted the driver then cd to that directory make clean works fine but when I peform make 536 this error occurs

[craig@localhost linux]$ make 536
Module precompile check
Current running kernel is: 2.6.8.1-12mdk
/lib/modules... autoconf.h does not exist
please install kernel source
make: *** [check] Error 1

any help would be greatley appreciated. Other than this (damn winmodems) I must say my first experiences of Linux are brilliant.

Dear gizmosarmy,

You need to install the kernel-source for your OS.
You would most probably find it on the CD, already installed on the system, or on the Internet. (Cd is usally best). You will also follow instructions on how to configure the kernel-source before using it. The most common place is /usr/src/linux-2.6 where you should follow the readme file.

Thanks manhinli, I've configured the kernell source and the installation goes much further however this error now occurs on the make 536 command

/home/craig/linux/coredrv/coredrv.c:286: warning: 'power_callback' defined but not used
make[3]: *** [/home/craig/linux/coredrv/coredrv.o] Error 1

Failed to build driver

Although i can't help you, gizmosarmy, I have encountered nearly the same problem trying to setup a 536ep modem. I am in the middle of my third try.

Can somebody out there help us???

Anybody who needs a simple Install-Detect-Ready solution should think about Xandros...

See my post at:
http://www.linuxquestions.org/questions/showthread.php?s=&threadid=308764

:)

Well doesn't work for me on RH9 ..........i don't know y......
i tyried everything ..........it always gives Error 8 at dialing...
i think its some sort of script error..........

Asked for help on LQ but of no avail..............

I have found out that it is now possible to use the 536ep modem with KNOPPIX 4.0.2.

You can see my post: http://www.linuxquestions.org/questions/showthread.php?s=&threadid=316552 and follow the instructions there.

Purchased an off-brand card with this chipset, and it worked without a hitch on Xandros 3 (instantly recognized).

Very good throughput on marginal phone lines.

I had some trouble at first using the 536ep on Slackware 11, but after some fiddling I got it to work, including starting/becoming active during boot. On occasion it took two attempts to get the modem to dial out if I just rebooted, I simply closed KPPP and reopened it, and presto, worked perfect.
I did NOT however use the closest-recommended source for the driver for my distro. I downloaded about 6 modem drivers for the 536ep and started trying them out. NONE of them mention compatibility for Slackware, but with Slack-11 & 2.4.33.3, I finally settled on the Intel-536ep-460.1-tgz driver from the intel site. I am currently downloading a few more, because I just compiled a 2.6.17.13 kernel and am using it now (I had to log in on the old kernel and reinstall the driver to use the modem) but I will update after I (hopefully) get the driver working with 2.6.17.13.
PS--- Put the 536ep-boot file into your RC.MODULES.LOCAL file if possible, it doesnt seem to like to boot when it is installed as per the instructions.

SV
PPS-- Almost forgot, I had to redo all of the HAYE commands in the KPPP dialogue of the modem settings/commands, when I update, I 'll post that too.

OK, Finally!!! Some brilliant character has come up with a reliable driver for the Intel536ep using a 2.6.20 kernel. I haven't tried it with other 2.6 kernels, but of over 20 different drivers I have tried, which wouldn't even compile, this one compiles, and WORKS!
Note: you likely will need to make the /dev node yourself (240,1 I think. read the readme.txt) and must modprobe the module yourself, or in a boot-script. Here's the new release of the driver as of this writing:
Website:http://linmodems.technion.ac.il/packages/intel/Philippe.Vouters/
Direct link: http://linmodems.technion.ac.il/packages/intel/Philippe.Vouters/intel-536EP-2.56.76.0_23_02_2007.tgz

This puppy has kept me connected for about 5 years now with no troubles. Not bad for around $20. Module still compiles for me at 2.6.23.13. Did not test it yet with 2.6.24, but I saw they are removing a function that its module uses (pci_find_device ?) so it may need a touch-up again soon.

Update: Working up through 2.6.25.9, broken again at 2.6.26 due to large tty_driver.h changes and others. I asked on the Linmodems list, but so far no luck for 2.6.26 and up. Code I'm working with:
intel-536EP-2.56.76.0_2008_03_22.tar.bz2

Update #2: Working again through 2.6.26.x (2.6.26.3 tested), thanks to Jeff Pohlmeyer and the Linmodems list.

RE: The post above me,
I have had intermittent success with this crazy thing depending on exactly which 2.6 kernel I was using at any given time..
Until recently, 2.6.23.12 was no problem for the modem driver from Phillipe Vouteur (Sorry Phillipe for the spelling if I got the last name wrong) but as of 2.6.24, specifically now 2.6.24.4, it again fails to work. It builds (with one WARNING) but won't modprobe.
I went through the code but don't know enough to know what to look for to fix it.
The deprecated pci code in still around last I checked though.
Meanwhile, if anyone notices a new release of the driver for the >= 2.6.24 kernel, please do set us know ;)
