pxe booting netbsd-4.0 on a soekris net4501

[Jasper Wallace]

Hi,

It looks as if netbsd-4.0 dosn't build pxeboot_ia32_com0.bin by default. I
tried pxeboot_ia32.bin, but didn't get anything out of the kernel (the
usual 3775212+5222852+179092=0x8c1b0c loading stuff appeared, but no
copyright message).

Is pxeboot_ia32_com0.bin not being built cos the non-com0 should just cope
these days?

I can't interrupt the non-com0 bootloader due to the soekris combios not
implementing the bios call back thing the bootloader needs to do
the timeout countdown, so the timeout happens instantaneously.

You need to change the console device of your pxeboot_ia32.bin file
using installboot(8)'s -e and -o options (see man page for details).

Try passing installboot(8) a large timeout value (I set it to 50).

I think you turn pxeboot_ia32.bin into pxeboot_ia32_com0.bin with

installboot -e -v -o speed=57600,console=com0 pxeboot_ia32.bin

or similar...

Cheers,

For soekris, use 'speed=0' to use the speed set for the bios console.
