I am trying to use an SD card that is vFAT formated, and get the following error in the dmesg
[519817.142421] FAT-fs (sdc1): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
[519817.148761] FAT-fs (sdc1): codepage cp866 not found
Now I would like to use 437 as default and would need to know how to change that for the default kernel config.
And secondly it seems even if I modprobe cp437 and set the mount option it still cannot find the codepage.
