Ms-sys is available on recent SL LiveCD/DVDs or you can take the rpm for el4 from?/packages/ms-sys/. # ms-sys --mbr95b /dev/sdb Create a new partition (enter n): Choose Primary partition (enter p), Partition number (enter 1). The size of the partition should be at least as larger as the LiveCD/DVD you want to install on the USB device. Afterwards, change the type (enter t) of first partition (enter 1) to?W95 FAT16 LBA?(enter e), and make first partition?active?(enter a and select 1). Before writing the partition table to the USB flash drive (enter w), you can print the changed settings (enter p). # fdisk /dev/sdb Command(m for help): n (新分区) p 1 1 (必须为1) 60 (启动盘空间大小，跟距实际需要填) t (改变分区格式) e (FAT16格式) a (做为启动盘) 1 w (保存修改) Now format the first partition (/dev/sdb1) as FAT16. If you like, you can set a label with option -n # mkdosfs -n SL-LiveCD /dev/sdb1 下载syslinux : /pub/linux/utils/boot/syslinux/ # wget /pub/linux/utils/boot/syslinux/3.xx/syslinux-3.82.tar.gz # tar xfvz syslinux-3.82.tar.gz # cd syslinux-3.82 # make # cd linux # ./syslinux /dev/sdb1 此时重启从USB 启动应该会出现(不出现就要重做上一步，出现拔出U盘重新开机进生下一步): SYSLINUX 3.11 2005-09-02 EBIOS Copyright (C) 1994-2005 H.
