I downloaded the Debian amd64 netinstall ISO and placed it on a USB stick using
dd if=debianblahblah.iso of=/dev/sdb. The installer works fine, but my laptop requires proprietary wireless drivers (RTL8192) to get internet during the install.
I extracted the drivers from the
realtek folder in the
firmware-nonfree package. I wanted to put them in the
/firmware folder on the install disk, but the it's not writable. So (following various instructions found online) I then tried to create a second partition in the remaining space on the drive (partitioned/formatted as VFAT), and move the files there. But I can't mount the partition, and receive
error "mount: wrong fs type, bad option, bad superblock on /dev/sdc3, missing codepage or helper program, or other error" if I try to mount the new partition.
I also tried placing the files on a separate USB, but the Debian installer couldn't find/detect them (and unfortunately, the installer isn't designed to give any info on why it failed).
How do I include the
rtlwifi drivers on the same disk as the debian ISO so that the installer can find them? Or alternately, how do I make a 2nd USB disk that the installer can recognize?
