In Marcnesium's tutorial there's a note about nvram setting to apply after oleg firmware installation, to increase nvram to 32Mb.

Code:
nvram set sdram_init=0x0009
nvram set sdram_ncdl=0
nvram commit
reboot
Now I have to replace Oleg's firmware with the original Asus fw, cause I'm reselling this router (I have another one running with Oleg's fw !!!).
Should I go back with other nvram settings or reinstalling Asus's original fw will do all job for me ?

Thanks, Max
