So we can use this firmware for B1 hardware of D-link GO-RT-150N routers?
Code:
D-Link DIR-600 B1 / B2
First, as the page says, D-Link DIR-600 D1 is confirmed incompatible, that means there is not other dd-wrt firmware that you could use.
Secondly, these 'revisions' (A, B, B1, D.. etc..) for the same model create teh false illusion that there is little hardware difference between the revisions, that is not the case, sometimes these revisions mean a totally different SoC.
Finally, and I could've just put this first and be done with it, ANY router that has less than 4 MB flash is incompatible, doesn't matter what chipset it is. Simply put, it's impossible to put DD-WRT on 2 MB. End of story.
