Greetings!
We have a couple of Mylex 33MHz 386s running Interactive's
UN*X. Occasionally, the console will hang in a strange state,
graphics or somesuch. I'd really like to reset it from elsewhere,
y'know? I hate to re-boot all the time. The console is a Relisys
RE5154E EGA color, and the card is an AutoEGA from STB Systems.
Also, we've a Western Digital WD8003E Ethercard Plus that also
sometimes hangs. I'd like to be able to software reset that, too.
I've tried the sequence:
fd = open ("/dev/wd", O_RDWR);
ioctl (fd, LDRESET, (char *) 0);
only to have ioctl return "Invalid argument". I suppose it really
wants some sort of parameter, but I've no idea what. LDRESET is
only mentioned in passing in llc(7) of the "386/ix TCP/IP Guide".
wd(7) doesn't mention board-level reset at all.
Help!
Danny
