Hi,
How about the following patch to src/sys/i386/isa/wd.c ? It fills in the
disk model name (and disk type) when reading the in-core disk label via
the DIOCGDINFO ioctl(), if it has not already been set. Tested and
working on a couple of machines. It's just a simple way for userland
programs to identify IDE disks by name (which is what I need for a
FreeBSD installation program).
Best regards,
Sebastian Lederer
