xt bios造句

• The XT BIOS added a few technical improvements over the 5150 BIOS, including displaying a memory count during the POST instead of a blank screen.
• The operating system usually sold with the XT was BASICA program that was included with DOS depended on the BASIC ROM . The XT BIOS also displayed a memory count during the POST, unlike the PC.
• In the interest of faster booting ( a fully loaded 5150 with 640k could take over half a minute to complete the POST memory scan ), the XT BIOS only attempts to read one bit each from the leftmost chip in each bank and if so, assumes that bank is filled.
