Last week a former NEC engineer who worked on
NEC arc mips hardware sent me a ImageStation (PICA)
so I could  correct  my NetBSD 1.5 installer.

A ready to burn/install and go CD image for
hardware supported by 1.5 release (not  NetBSD-current 1.5)
is available at ftp://guiduck.com/incoming/netbsd/arc/cd15.iso .

Brief Installation Instructions ...
1. Arc Menu Item ->Run a program -> cd:\install
2. Use two partions (ie use part of drive for NetBSD),
    NetBSD is first partion starting at cylinder 0.
    MSDOS is second partition make 10 - 15 megs to hold
    several kernels (for testing).
3.Select 'custom' bsd labeling, add msdos partition
4.Continue on select sets to install...only required are
   kernel,base,etc.
5.Exit to command line
6. format the msdos partition with command line similar
to following : newfs_msdos -F 16 /dev/rsd0f
7. mkdir /msdos
8. mount_msdos /dev/sd0f /msdos
9. mount_cd9660 /dev/cd0a /mnt
10.cp /mnt/netbsd.eco /msdos/netbsd.eco
11 umount -a
12 reboot ( the 'command' ie don't pull the plug !)
13 Add 'arc' menu item with "manage menu"
the osloader program is netbsd.eco .

===================================
Magnum's don't display with 'generic' kernel instead
require custom kernel "PCCONS".  The 'pccons'
install image and kernel is in subdirectory pccons
(ie cd:\pccons\install and cd:\pccons\netbsd.eco).
