先看看 /usr/include/sys/scsi/autoconf.h 中有关 SCSI_OPTION 的参数 :
#define SCSI_OPTIONS_DR 0x8 /* Global disconnect/reconnect */
#define SCSI_OPTIONS_LINK 0x10 /* Global linked commands */
#define SCSI_OPTIONS_SYNC 0x20 /* Global synchronous xfer capability *
#define SCSI_OPTIONS_PARITY 0x40 /* Global parity support */
#define SCSI_OPTIONS_TAG 0x80 /* " tagged command support */
#define SCSI_OPTIONS_FAST 0x100 /* " FAST scsi support */
#define SCSI_OPTIONS_WIDE 0x200 /* " WIDE scsi support */
#define SCSI_OPTIONS_FAST20 0x400 /* " FAST20 scsi support */
看到了吧, 如果你想 enable 某个 function, 那就把它 add 起来(注意是
HEX !), 然後在 /etc/system 中加一行 :
set scsi_options = 0x(你的数值),
reboot 就行啦 :)
