The Soekris redirects the VGA BIOS characters to the COM port. Hence you get them twice. (2) The 16-column line wrap is a bug in the Soekris VGA BIOS emulation. You can patch and rebuild pxelinux.0 to avoid this, by stopping pxelinux writing to the VGA BIOS. Details at the end of http://archive.netbsd.se/?ml=soekris-tech&a=2007-11&m=5685776 and the patch, with instructions on how to rebuild pxelinux.0 using nasm, is higher up. If I remember rightly, this patch will also prevent the character duplication. Just for reference, here's a working pxelinux.cfg/default: serial 0 19200 0x303 label linux kernel openwrt-x86-2.6-vmlinuz append initrd=openwrt-x86-2.6-rootfs.cpio.gz init=/etc/preinit console=tty0 console=ttyS0,19200n8 And here's a working grub/menu.lst (with settings to allow the unit to boot even when no serial cable is connected) serial --unit=0 --speed=19200 --word=8 --parity=no --stop=1 terminal --timeout=0 --dumb serial hiddenmenu default 0 timeout 0 title OpenWrt root (hd0,0) kernel /boot/vmlinuz init=/etc/preinit console=tty0 console=ttyS0,19200n8 reboot=bios initrd /boot/rootfs.cpio.gz boot However, fixing the character output problems is mostly cosmetic. It won't solve the problem of the missing kernel.
