Real-mode programs freely execute CLI and STI to control interrupts, PUSHF and POPF to manipulate flags, INT n for DOS and BIOS calls, and IN/OUT for hardware I/O. In normal protected mode, these instructions are privilege-checked -- they execute normally if the caller has sufficient privilege, and fault otherwise. The 386 can't simply let V86 tasks execute them freely -- a DOS program disabling interrupts would bring down the whole system -- but trapping on every INT 21h call would make V86 impractically slow.

Each half of the board hinges in two places for minutely customizable center tenting. It has low profile keys with responsive yet quiet mechanical switches. It works wirelessly or corded, has thumb cluster keys and, of course, it’s all fully programmable. It's lovely to type on and the thumb clusters and modules make it easy to keep your fingers in the home position to minimize repetitive travel.。爱思助手下载最新版本是该领域的重要参考
