Syslinux - Aug 2006 - What method can I use to configure PXE client(msdos) output console from serial port?

Hi,

    How are you!

I built a PXE server of MSDOS in Linux server, client can boot from network and
login MSDOS, but by default, the output console is VGA,

My target client has not VGA port, it can only output from serial port, so could
you help to tell me how to boot a MSDOS client from network and keep the PXE
client output console is serial port ?

 Below is the PXE configure file?s content:

Vi /tftpboot/pxelinux.cfg/default

 

Kernel memdisk

Append initrd=dos.img

 

 

Note: dos.img is a DOS bootable disk image, ( dd if=/dev/fd0 of=/dos.img )

 

Thanks

IMHO, this is a DOS related issue.
Something like above should works.
