Hi, all This is my pxe config file: DEFAULT test LABEL test KERNEL test/yast-SLES8.1-GA-i386z APPEND load_ramdisk=1 initrd=csm/yast-SLES8.1-GA-i386.gz ramdisk_size=65536 autoyast=nfs://172.20.3.2//netinstall/csm/1.4.1 /autoyast.SLES8.1/172.20.3.25.xml install=nfs://172.20.3.2 /netinstall/Linux/SLES/8.1/i386/GA/ ip=172.20.3.25 netmask=255.255.255.0 acpi=oldboot netdevice=eth0 As I know, pxe cmd line passed to autoyast will be cut by kernel to no more than 256 chars, but last line in my config file is far more than 256 chars, how can I pass the line to autoyast without being cut? Info file is not exactly what I want because I have to prepare different initrd for different machine.
