You require a null modem cable to connect to it, however. As I recall, PMON will output its debug messages via the serial port by default, but I haven't tried actually configuring the Fuloong from the RS232 port. I've uploaded a photo of the connector at http://lebesgue.cowpig.ca/~philippe/fuloong_rs232.jpg, in case that helps. As a side note, I think deblobbing PMON will be fairly simple -- just delete the file with the VGA BIOS code in it (vgarom.c in the Bonito directory, under Targets) in it and then disable the config option that enables VGA output (probably commenting out 'select mod_vgacon' in the Bonito config will be enough, but I haven't tried). Cheers, Phil [ ... Later djbclark writes ...] On IRC today, Philippe told me that he tried quickly to disable the VGA console in PMON, but that a lot of the nice barriers that are supposed to modularize PMON were not respected in code that was added to support the fuloong and yeeloong (eg the diff between upstream PMON 2000 and the version that works on the Lemote boxes), so actually removing the VGA console support and related blob may be difficult (at least for someone who hasn't worked with that code a lot - perhaps it would be easier for whomever did the Lemote changes in the first place.) -- Daniel JB Clark | Free Software Activist | http://pobox.com/~dclark -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
