What needs to be done to enable 32 bit I/O transfer mode for (E)IDE disks, on a system running a 2.4 series Linux kernel?

A. The Linux kernel must be recompiled.
B. The sysctl utility must be used.
C. The hdparm utility must be used.
D. This feature isn't supported in 2.4 series kernels.
E. This feature is enabled by default in 2.4 series kernels


「hdparm」指令可以取得或是設定SATA或是IDE裝置的參數,「-c」參數可以取得或是設定(E)IDE 32-bit I/O的支援。所以答案是選項C。
