Re: Multiboot trouble (nt boot loader)

Nick, thanks for the response.

Sorry, missed couple of steps - the file gets ssh-ed to a linux box,
then PuTTY-ed to windows. No problems here.
But as I found out, dd here produces 512 bytes of nothing, zero:

    dd if=/dev/rwd0a bs=512 count=1 |hexdump -C

    0000000 0000 0000 0000 0000 0000 0000 0000 0000  |................|
    *
    0000200

And that's _after_ I upgraded to 4/20 snapshot.
Am I reading the wrong disk? I only have one ;-) see attached dmesg.
It's ether me doing some stupid thing, or "select is broken",
which I highly doubt.
Here are my mounts, fdisk and disklabel outputs attached:

    /dev/wd0a on / type ffs (local)
    /dev/wd0h on /home type ffs (local, nodev, nosuid)
    /dev/wd0d on /tmp type ffs (local, nodev, nosuid)
    /dev/wd0g on /usr type ffs (local, nodev)
    /dev/wd0e on /var type ffs (local, nodev, nosuid)

I should probably mention that previously I had Gentoo on
that partition with Grub for the bootloader, so I restored
windows mbr by booting to win95 dos from floppy and doing "fdisk /mbr"
All nice but first win2000 boot after that said it found/installed
a device (what device?) and asked to reboot. Reboot ..., w2k lost drive
letter assignment on the second partition, had to restore it.

Again, any help would be appreciated. Thanks.
