#1 [NetBSD] KuroBox Pro now boots automatically from disk

On 2009/05/04 , I wrote
(7) PROBLEM
* Can't Boot stand alone for now.
Currently bootp server is necessary. Ext2fs and uImage may be one of the work around.
This is now resolved. The points will be
  1. Have Native Linux partition (131 = 0x83) by using fdisk
  2. By using mkfs.ext2 from pkgsrc/e2fsprogs, make file system
    /usr/pkg/sbin/mkfs.ext2 /dev/wd0h
    
  3. place netbsd-arm.bin (by objcopy -O binary) under its ext2fs partition
  4. (in u-boot environment) set bootcmd variable as
     setenv bootcmd 'ide reset; ext2load ide 0:4 8000 /netbsd-arm.bin; go 8000'
    
    (saveenv to save above setup permanently after the setup confirmed correct.)
That's it, I believe.

The first of all, I selected 'Use the Entire disk' at original sysinst installation. The last partition was for /export and I might have newfs even after installation to make room for small boot area. So I decided to divide the last partition into /export and another fdisk area.

See, the 'h' partition is outside of 'c'. fstype 4.2BSD was necessary to issue newfs (mkfs.ext2) from NetBSD environment. Original size of c was 15631488.
  156301488	original size of 'c'
-     61488	room for fdisk #3
  ---------
  156240000	the size of 'c' after shrink
fdisk looks below: ( 'fdisk -u wd0' to update (modify) the size of partition.)
kuroarm# fdisk wd0
fdisk: Cannot determine the number of heads
Disk: /dev/rwd0c
NetBSD disklabel disk geometry:

BIOS disk geometry:
cylinders: 1023, heads: 255, sectors/track: 63 (16065 sectors/cylinder)

Partition table:

    start 156240000, size 61488 (30 MB, Cyls 9725/125/1-9729/80/63)
First active partition: 0
kuroarm# 
In ext2fs file system, the kernel is placed.
kuroarm# mount -t ext2fs /dev/wd0h /mnt
kuroarm# ls -l /mnt

-rwxr-xr-x  1 makoto  wheel  5061572 May  4 17:26 netbsd-arm.bin
kuroarm# 
dmesg for 5.99.01
Even with this setup, naturally, the human intervension required as:
boot device: <unknown>
root device: wd0a
...
init path (default /sbin/init):  (Return)
So I may need to re-config the kernel or have some setup to pass the booting PATH to the kernel.

pkgsrc related::

I have a problem making digest-20080510.
kuroarm# cd /export/pkgsrc/pkgtools/digest/
kuroarm# make
===> Skipping vulnerability checks.

kuroarm# 
So I did:
export PKG_PATH=ftp://ftp.jp.netbsd.org/pub/pkgsrc/packages/NetBSD/arm/5.0/All
pkg_add digest

Suggestion for sysinst:

You probably need to select 'Edit the MBR partition table' at sysinst MENU (sorry for the text in Japanese).
