Making it Work

Firmware

You can use the driver for windows as well as for linux. When you install this device on your windows computer, installer in the CD-ROM will install 'isdbt_nova_12mhz_b0.inp' into the c:¥windows¥system32. You can copy and use this file to your linux firmware folder (ex. /lib/firmware).

Drivers

The driver comes with linux kernel drivers/media/dvb/siano/. However this driver needs a patch. You need to set SMS_SIANO_MDTV in the .config file during the kernel rebuild process.

Patch for Kernel Source

This is a patch for kernel version 2.6.35.10.
