If you have a Guru ROM it will assume the 33C93A is still running @ 7 MHz.
EDIT: The 33C93A_14MHz Util does NOT seem to work with the Guru ROM so you should use rdbctrl to set the RDB flag to ASYNCHRONOUS or for versions 6.11+ setting JP5-4 on disables the initial SDTR. Another option is to install a jumper block to switch back to 7 MHz if you really want to enable SYNCHRONOUS mode.
(Sorry this Util was a quick hack for the C= 7.0 ROMs).
P.S. If you don't have a Guru ROM but you have something faster than a stock 68000 see this thread:
