*sigh*
250+ questions about wdc1 probing incorrectly from 2.1.0 through
3.0-RELEASE on -questions, -bugs, and -hardware, and still I haven't seen
an *answer*. This definately qualifies as a FAQ, so why isn't it in the
FAQ pages?
Anyway. I'm asking again, and I'll put the answer up on the net somewhere
once I figure out what the problem is.
anyway.. I'm running FreeBSD 3.0-RELEASE installed fresh from ftp.
the boot floppy can't find wdc1 and neither can my custom kernels. my
2.2.6 box was able to see wdc1 until i supped it to 3.0 and then it stopped
seeing wdc1 as well! Where's this flakiness coming from? It's like it's
a misconfigured variable or something simple, yet deeply hidden.
so, the nitty gritty details.....
