为了在 S/390 上安装系统，需要一个工作的网络设置和 ssh 会话。
引导过程开始时候要求一些网络参数来进行网络设置。如果设置是成功的，您将会通过一个 ssh 会话登录进入系统，并且开始一个标准系统安装。
On S/390 you can append boot parameters in the parm file. This file can either be in ASCII or EBCDIC format. It needs to be fixed-width with 80 characters per line. A sample parm file
parmfile.debian is provided with the installation images. If a parameter is too long to fit into the 80 characters limit it can simply be continued in the first column of the next line. All the lines are concatenated without spaces when being passed to the kernel.
If you boot the installer in a logical partition (LPAR) or virtual machine (VM) where a lot of devices are visible, you can instruct the kernel to restrict the list to a fixed set of devices. This is advised for the installer's boot process if a lot of disks are visible, most likely in LPAR mode. The “cio_ignore” option supports both a blacklist (to only disallow a few devices) and a whitelist (to only allow specific devices):
# blacklist: just ignore the two devices 300 and 301 cio_ignore=0.0.0300-0.0.0301 # whitelist: ignore everything but 1150, FD00, FD01 and FD02 cio_ignore=all,!0.0.1150,!0.0.fd00-0.0.fd02
Please note that all devices numbers' hex digits need to be specified in lower case. Furthermore if this boot parameter is used all devices need to be listed: this includes at least disks, network devices and the console. To be considered during the installer's boot process the above option needs to be added to
