NetBSD/alpha 6.99.38

This menu-driven tool is designed to help you install NetBSD to a hard disk,
or upgrade an existing NetBSD system, with a minimum of work.
In the following menus type the reference letter (a, b, c, ...) to select an
item, or type CTRL+N/CTRL+P to select the next/previous item.
The arrow keys and Page-up/Page-down may also work.
Activate the current selection from the menu by typing the enter key.

I found only one disk, sd0 (68G, FUJITSU MAU3073NC).
Therefore I assume you want to install NetBSD on it.

NetBSD uses a BSD disklabel to carve up the NetBSD portion of the disk into
multiple BSD partitions. You must now set up your BSD disklabel.
 
You can use a simple editor to set the sizes of the NetBSD partitions, or
keep the existing partition sizes and contents.
 
You will then be given the opportunity to change any of the disklabel fields.
 
The NetBSD part of your disk is 82858 Megabytes. A full installation
requires at least 384 Megabytes without X and at least 434 Megabytes if the X
sets are included.

You can now change the sizes for the system partitions. The default is to
allocate all the space to the root file system, however you may wish to have
separate /usr (additional system files), /var (log files etc) or /home
(users' home directories).
 
Free space will be added to the partition marked with a '+'.

I guess this problem caused by Tru64 UNIX's disklabel is the same format as BSD 
disklabel.

If Tru64 UNIX's disklabel is stored, internal processing is:

        dlcyl = disklabel.d_ncylinders;
          -> 49158 ("cylinders")
        dlhead = disklabel.d_ntracks;

        sectorsize = disklabel.d_secsize;
          -> 512 ("bytes/sector")
        dlcylsize = disklabel.d_secpercyl;
          -> 3452 ("sectors/cylinder")

        /*
         * Compute whole disk size. Take max of (dlcyl*dlhead*dlsec)
         * and secperunit,  just in case the disk is already labelled.
         * (If our new label's RAW_PART size ends up smaller than the

        dlsize = dlcyl*dlhead*dlsec;

        if (disklabel.d_secperunit > dlsize)
