Joker_cn

今天修改了
其中关于usb文件系统，usb鼠标，usb键盘,raid我删去了，
还有对硬盘的数量修改了
起动后没问题

# Multiple sector I/O. a feature of most modern IDE hard drives,
# permitting the transfer of multiple sectors per I/O interrupt,
# rather than the usual one sector per interrupt.  When this feature
# is enabled, it typically reduces operating system overhead for disk
# I/O by 30-50%.  On many systems, it also provides increased data
# throughput of anywhere from 5% to 50%.  Some drives, however (most
# notably the WD Caviar series), seem to run slower with multiple mode
# enabled. Under rare circumstances, such failures can result in
# massive filesystem corruption. USE WITH CAUTION AND BACKUP.
# This is the sector count for multiple sector I/O - the "-m" option
