I tried to serial boot my TS-7200 today. Its watchdog is set for 1 second. So
it's impossible to serial boot it without hardware modifications, (or a CPLD
reprogram).
The EP9301 on my board downloads the serial boot program at 9600bps. It can
only load 960 Bytes in one second. Not even half of the 2048 Bytes needed to
load the SerialBlaster Boot loader.
My board is a TS-7200 Rev B.
