To whom it may concern: I would like to share my experience in getting a pci modem intranet connection with Fedora Core 6 x86_64. Computer specs: Dell XPS Gen 2 desktop with 3.4Ghz Intel P4 HT processor, 1GB ram, 250GB HDD, NVIDIA G-Force 6800 video card. It has a multi-boot setup including: Windows XP Media 2005, Windows XP Pro, Mandriva Le 2005, and the latest Fedora Core 6 x86_64. I use a boot manager called Bootitng which does everything Partition Magic or the later "Norton Ghost" can do and more. With Bootitng I create a compressed image of all the Operating systems which are stored in the data partition. The HDD has a 100GB partition for data and the Windows partitions are 15GB. The Linux partitions are allocated 25GB but are built on 10GB partitions and expanded with resize2fs to their 25GB size after they are built to ship shape, reason being it only takes less than 10 minutes to wipe out the installation and re-load the image of a fresh install when things go wrong on a 10GB partition, instead of the traditional method with CD or DVD rebuild from scratch, and it is much faster to use this method than to back-track and try to undo your mistakes some times. I started downloading FC6 on Dec. 03 2006 with Bittorrent from my Mandrake Le i686 and did not stop it till it finished around the 18th of Dec. 2006 with the Dell supplied Intel 537ep modem, upon first installation it became clear that I would not be able to put FC6 on-line with the Intel modem so I put a Lt 1648t00 modem in another slot and had it on-line within a day or two with the martian kit using a martian_modem built in Mandrake using the ltmdmobj.o-8.31-gcc3.gz as Mandrake LE comes with gcc 3, how that happened became a puzzle later on as I had saved a copy of it and tried using it again to no avail. PS: I was never able to get it on-line with wvdial, only through Administration/Network or KPPP, wvdial would show "pppd *" or "pppd >" which was unusual and appeared to connect but nothing but errors when trying to surf or do anything on the intranet, and eventually would exit with error code 16. I then decided to start from scratch again as the first installation had both Gnome & KDE desktops and because I never use Gnome and the list of updates was huge, I omitted Gnome and tried again with a more customized set-up. With my easy wipe & re-load system with bootitng I was never able to transfer any packets on the intranet after at least 120 tries using an arsenal of martian_modems stripped and un-stripped built in Mandrake using gcc 3 & gcc 4 with both ltmdmobj.o-8.31-gcc3 & ltmdmobj.o-8.31-gcc4 inserted before the #make install command and inserted directly in /usr/sbin without the #make install step, it would at times appear to connect but "no dice". On New years eve I took a break and treated a friend with some Saskatoon wine and he shook his head at me saying I'm wasting my time, just use your Windows and carry on, to hell with those 64 bit Linux, (he sets up computers for the government of North West Territories here in northern Canada, all Windows of course). I told him how I noticed FC6 had some updates that I wanted to apply and try again as one of these updates is for irqbalance which is integral to this martian approach. So after recovering from the hangover the next day I jumped right back in and updated the kernel to the so-called final version and updated every network related .rpm including irqbalance, iproute, etc. and built the martian kernel mod only, and inserted the Mandrake built martian_modem with gcc4 and ltmdmobj.o-8.31-gcc4 in /usr/sbin, and did not go through the ,/automate steps and decided to just issue the martian_modem command without automation and finally was able to surf, (most often this was the route I took: not doing the automation) But after half an hour the speed went from 3Kbps to 1Kbps and it took an eternity to do a small update. After a couple days of frustrating troubleshooting I exchanged that Lt 1648t00 modem with a Lt 1646t00 modem with the mars chip and managed to maintain an average of 3Kbps speed while doing updates. The Intel 537ep modem as with ESS, Pctel, Motorola etc. usually run at 4.4Kbps min on this line so I removed the 1646t00 unit and put in my last Lt modem that I knew was good as Mandrake was using it successfully in the past and brought the speed up to an average of 4.0Kbps, (another 1648t00 modem.) As of this writing,Jan 09, 2007, I finally applied all updates and went back into the scripts folder and ran the ./automate.sh commands and made a compressed image, deleted previous images and re-booted, tried to go back on-line and to no avail, I was not able to re-connect, I wiped out the partition and re-loaded the image and still no intranet, NO CARRIER, NO DIAL TONE, etc. etc. etc. Three weeks, day in, day out, non stop, every waking hour, down the toilet, start over, was what was going through my head but then I remembered the last thing I did, running those automation commands recommended in the martian kit, I tried running the remove_outdated.sh command and re-booted. NO intranet. So I went into system/services in FC6 and un-checked martian and hit "save", re-booted, and got back on-line and wrote this blurb. Either there is something funny about those automate scripts regarding FC6 or I have another underlying problem with my unit. I sometimes feel FC6 x86_64 destroys Ltmodems, but this third unit is holding it's speed thus far. Still cannot establish a successful link with wvdial, a sample of it's output follows, (this is with added line Carrier Check = no). --> Modem initialized. --> Sending: ATDT645-6839 --> Waiting for carrier.
