Hi,

I'm new to OpenWrt, I have a Rosewill RNX-N150RT, and I'd like to know a bit more before I break out the soldering iron:

1) Since this board is effectively a TL-WR741ND, can I add USB to it like in the instructions here: http://wiki.openwrt.org/toh/tp-link/tl- … b.host.mod

2) I don't know if I have room to solder there, so what's a good way to remove the heatsink from the CPU?  It feels like it's glued on and I don't want to rip the chip off the board trying to twist it off.

3) Can I replace the S25FL032P SPI flash chip with a pin compatible 64/128/256mbit one to increase storage space?  (I know I'd need to copy the chip contents over with an EPROM burner, but would anything else need to be done software-wise?)

4) If I do the SD card mod, does it matter which GPIOs I use?  Can I use all LEDs, or will data out from the card need to go to something already used as an input (a switch)?

5) Is there much point in doing a RAM upgrade or is 32MB already a decent amount to work with?

6) Are there any other usable interfaces on the AR7240 CPU that OpenWRT can get at?  (SPI, I2C etc)

Thanks!
