I doubt it, F1 would have booted the first partition of wd0, and F5
thembr of wd1. You ould have a menu name for F1, but not F5.

This will be because there are no names in the menu table.

RTFM (and the display!) the keys got changed, F1 boots the mbr from disk0,
and F2 that of disk1 (etc). You need to type '1' to get the first bootable
partition of the current disk booted and '2' for the second (dense numbering).
This was changed because you can now boot netbsd from an extended partition
and there can be more than 4 menu ites.

The bootselect menu strings are now configured whith the partition parameters.

Yes - you have to have boot blocks on wd1, getting wd1 booted is your problem!
If you install the netbsd mbr onto wd0, then (now) F1 will boot wd1.

I'm not actually sure windoze will like you moving the disk from disk0
to disk1....
Run netbsd's fdisk on your windoze disk, edit ptn 0 and set a boot menu
name.
Swap the disks back.
Then '1' will boot windows and F2 netbsd on the other disk.
You may want to force /usr/mdec/mbr to be used on the netbsd disk.
(since you don't want a bootmenu for that disk displayed.
