I recently acquired an ATI HDTV Wonder PCI card from a friend of mine and decided to test it out on my satellite TV transcoding server to also get OTA channels. I am using a generic linux kernel version 2.6.29.2, and it detects the card just fine, but needed a firmware file for the front-end. I checked the get_dvb_firmware script, but it failed because the driver pack from AVerMedia is no longer available. I then tried to get the latest drivers from them by hand for the A180 card, which also has the nxt2004 demod/frontend.. but the driver package refused to install on my WinXP system. After some quick googling and not finding the nxt2004 firmware downloadable online, I tried to find it in the AMD/ATI driver package instead. It was not readily apparent which file had the firmware, and the only files in the package were windows executable/system files. So I figured it was embedded in one of these files.. I was able to find the nxt2002 firmware file, and compare it to the contents of the file "atidtuxx.sys." In this file, I fiddled around with offsets and dumping 8kb chunks out and feeding it to my linux machine's kernel, and magically got my tuner card to APPEAR to work properly with it, but I do not know the firmware's actual size, so there's a distinct possibility that I'm sending it extra garbage it doesn't need. Default extraction path from nullsoft installer: C:\ATI\SUPPORT\6-1_hdtv_83-2036wdm\WDM_XP Firmware appears to be in ATIDTUXX.SYS at offset 0x681E, taken as a 8192byte chunk. To help me with my findings, does anybody have a known working version of dvb-fe-nxt2004.fw that I can use for comparison? Thanks! And if I have found the correct firmware, the get_dvb_firmware script can be updated to pull this from the ATI drivers now.. If I did this the hard way, you may feel free to point this out as well :) --Mike _______________________________________________ linux-dvb users mailing list For V4L/DVB development, please use instead linux-media@xxxxxxxxxxxxxxx linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
