I just got a TTL-serial cable going & I'm wondering a few things..
First, how did you break into YAMON in order to netboot? I've tried ^C, ^Y, etc. It may be that I'm just not fast enough..
Next, any progress on either kexec, or tricking it to boot an unencrypted kernel from flash?
Last, dmesg talks about a SATA port. When I opened the box to install the TTL/Serial cable, I noticed another, smaller 4-pin header right next to the heatsink (in addition to the serial header along the edge of the board). Is that second header for SATA?
