[. . . ] DOS systems have an address space of 1 MB, but the top 384 KB (called high memory) is reserved for system use. This leaves 640 KB of conventional memory. Everything above 1 MB is either extended or expanded memory. Refers to memory above and beyond the standard 1 MB base memory that DOS supports. Extended memory is only available in PCs with an Intel 80286 or later microprocessor. Extended memory is not configured in any special manner and is therefore unavailable to most DOS programs. However, Windows and OS/2 can use extended memory. Shows the total base and extended memory available on the system. The memory size is automatically detected by BIOS during the power-on self test (POST). If you install additional memory, the computer automatically adjusts this parameter to display the new memory size. Extended Memory Total Memory 26 IDE Primary Master/Slave and IDE Secondary Master/Slave Setup English The following table describes the parameters found on this submenu. The settings in boldface are the default and suggested settings. Item IDE HDD Auto-Detection IDE Primary Master Description Auto-detects your hard disk. Format/Options [Press Enter] Displays the device type. Auto None Manual Auto Large LBA CHS xxxxx MB 0 to 65535 Access Mode Selects the hard disk access mode. Capacity Cylinder Shows the size of your hard disk in MB. The PIO mode specifies the data transfer rate of the hard disk. For example: mode 0 data transfer rate is 3. 3 MB/s, mode 1 is 5. 2 MB/s, mode 2 is 8. 3 MB/s, mode 3 is 11. 1 MB/s and mode 4 is 16. 6 MB/s. Setting these items to Auto activates the hard disk speed auto-detect function. If your hard disk performance becomes unstable, you may manually set the system to a slower mode. Caution: It is recommended that you connect the first IDE device of each channel to the endmost connector of the IDE cable.
