Can't find init when booting 5.0 install CD with serial console

[Ray Phillips <r.phillips%uq.edu.au@localhost>]

I made a CD from this .iso image:

  ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0/i386/installation/cdrom/boot.iso

then booted a PC from it, chose option 4 from the boot menu to get a 
boot prompt and executed 'consdev com0' so I could capture the 
console output.  It failed to get as far as running sysinst because 
it couldn't find /sbin/init, as shown in the output below.

The CD works fine when just using the default setting, 1.

By the way, what do the other options in the consdev line mean?

consdev {pc|com[0123]|com[0123]kbd|auto}

`pc' just means the local video card and keyboard I guess.

`com[0123]' is obvious but what about `com[0123]kbd'  and `auto'  ?


Ray



1. Install NetBSD
2. Install NetBSD (no ACPI)
3. Install NetBSD (no ACPI, no SMP)
4. Drop to boot prompt

Choose an option; RETURN for default; SPACE to stop countdown.
Option 1 will be chosen in 0
type "?" or "help" for help.
>  consdev com0


Then this text appeared on the serial console:



Welcome to the NetBSD 5.0 boot-only install CD
===============================================================================

This CD contains only the install kernels. Binary sets to complete the
installation must be downloaded separately.

ACPI should work on all modern and legacy hardware, however if you have
problems, please try disabling it.

If you encounter problems on hardware manufactured after 1998 with ACPI
enabled, please file a problem report including output from the 'dmesg'
command.
