Hi,


for upcoming releases of OpenBSD, I would love to be able to
upgrade/install my good ol' Dell Inspiron 7500 with its Xircom PCMCIA
NIC over the network. Since we're not using 2.88MB floppy emulation
anymore, I was wondering if it would be possible to enable dc@cardbus in
RAMDISK_CD. My humble kernel configuration editing skills tell me that
the following patch (hope it survives inlining) works:

--- RAMDISK_CD.orig	Thu Jan 27 15:54:01 2005

This looks trivial enough, although I won't pretend to understand the 
kernel and possible complications because of this change. At least I did 
some testing - that is, I made a release and tested the resulting 
bsd.rd. First of all, my building log didn't show any "out of space" 
errors, so it seems to fit nicely. That was the result:

-rw-r--r--  1 root  wheel  4352600 Jan 27 17:34 bsd.rd

All I can say is "works for me", see the dmesg below that I transferred 
via FTP to another box so I can mail this to you - done within bsd.rd's 
shell after i've let upgrade.sh configure the network for me.
