I'm posting this from my freshly installed FreeBSD 2.1 system :-)
Took about a day and a half to go from blank disks to having a
workable system with a custom kernel, X, mail, news, and Netscape.

So, for my first stupid post to the group, I'd like to ask if anyone
has any idea why my 3C509 seems to be so slow?  I'm getting less than
100Kbyte/sec FTP from a Sun 10/51 to my 486/33.  This same configuration
was capable of 700-800K under Linux.

I saw the earlier post about the incorrect interrupt causing the driver
to poll, so I checked that.  The 3C509 is at I/O 0x300, IRQ 10, just
like the kernel thinks it is.  No other device conflicts with that.

Thanks in advance,
Richard Lamb
