I've done testing of this port-no-probe behaviour on both my AST/4 cards & the BOCA. Both of them have the _potential_ to fail a port's probe if DCD is set, but not all DCD-active ports fail a crash-reboot probe.. However, a port that has DCD _&_ either TX or RX at the crash is bound to fail the probe (ain't 100%, but certainly 75% probable ;) *Hmm* Could this be related to the 16550A's, or (as suggested) some code in the boot probe? > -- > Heikki Suonsivu, T{ysikuu 10 C 83/02210 Espoo/FINLAND, > hsu@clinet.fi work +358-0-4375209 fax -4555276 home -8031121 Rich. -- Richard Siggs admin@spirit.com.au Spirit Networks Pty Ltd http://www.spirit.net.au P.O.
