0. NetBSD/hpcmips kernel with sysinst

The bootloader and system installer for NetBSD/hpcmips is at:

ftp://ftp.NetBSD.org/pub/NetBSD/arch/hpcmips/snapshot/20000315/installation
[20000315 is snapshot release date. You should check for a newer version.]

Get these files in binary mode:
netbsd (the kernel)
pbsdboot.exe
pbsdboot.exe is a Windows CE applicaton. Start pbsdboot and
 - set hardware type (NEC MobileGear R500...)
 - kernel path. (\Storage Card\netbsd)

[WARNING! Booting NetBSD/hpcmips for the first time will erase the entire
contents of your memory, including the program memory and storage of your
Windows CE installation! Before you do this, be sure to do a complete
backup of your CE files.]

Click the "Boot" button to start NetBSD/hpcmips.

The NetBSD/hpcmips kernel and system installer takes almost 6MB of program
memory. If you get a "cannot allocate heap" error, adjust the memory
allocation in Windows CE here:

Start->Settings->Control Panel->System
Choose the Memory tab and move the slider toward the left to allocate more
program memory.

If the sysinst application fails, try the following steps:

1. CF partition
Run fdisk on the CF partition.

/dev/wd1a ffs   112M 
/dev/wd1b swap   10M 
/dev/wd1e msdos 5M

Tips:
To create a CE-readable msdos partition on CF:
    - Set the primary partition to sysid 6 in fdisk.
    - Set CF to Windows CE CF slot.
    - Windows CE will format the partition automatically.
    
fdisk command results.
      .........

disklabel command results.

disklabel wd0   --- print wd0 partition information
disklabel wd0 > label.CF  --- dump wd0 partition information
edit label.CF   --- edit wd0 partition information

The fdisk footprint from an example 128MB CF card:
#        size  offset  fstype [fsize bsize  cpg]
  a:   209920    4352  4.2BSD   1024  4096   16  # (Cyl.    17 - 836)
  b:    12800  214272    swap                    # (Cyl.   837 - 886)
  c:   222720    4352  unused      0     0       # (Cyl.    17 - 886)
  d:   227584       0  unused      0     0       # (Cyl.     0 - 888)
  e:     4320      32   MSDOS                    # (Cyl.     0*- 16 )

Typical fstab entry:
/dev/wd0a  /  ffs rw 1 1
/dev/wd0b none swap sw 0 0
/kern     /kern kernfs rw
/dev/wd0e /msdos msdos rw 0 0

2. newfs & mount PC
newfs /dev/wd1a 
mount /dev/wd1a /mnt
mount -t msdos /dev/wd1e /msdos2

tips:
pbsdboot.exe can find the /netbsd kernel on the CF card's ffs partition.
If your CF card has both msdos and ffs partitions, pbsdboot.exe can find
ffs:/netbsd from within Windows CE, and you won't need a second kernel
file on the msdos partition.

3. get the distribution
get base.tgz etc.tgz kern.tgz
ftp://ftp.NetBSD.org/pub/NetBSD/arch/hpcmips/snapshot/

4. copy kernel
tar xzvf kern.tgz
netbsd    - root wd0a swap wd0b

cp -p netbsd /mnt/netbsd
cp -p netbsd /msdos2/netbsd

5. copy pbsdboot
uudecode /usr/src/arch/hpcmips/stand/pbsdboot/pbsdboot.uu
cp -p pbsdboot.exe /msdos2/pbsdboot.exe

6. extract sets
tar xzvf base.tgz -C /mnt
tar xzvf etc.tgz  -C /mnt

If you have no room to stage the sets, these commands will let you extract
them directly via ftp:

cd /; ftp -o "|tar xpfz -" ftp://.....

7. make device nodes

cd /mnt/dev
sh ./MAKEDEV all

8. check /etc

cp /mnt/etc/fstab.wd /mnt/etc/fstab
edit /etc/fstab

edit /etc/rc.conf

rc_configured=NO  -> rc_configured=YES

9. Full installation

A complete build environment requires over 500MB of storage.
