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.
Just the other day, I chatted with someone who not only lost a drone (a big deal, but something the insurance will cover), but that drone contained a 1TB storage card with days of footage (something the insurance won't cover). 。业内人士推荐体育直播作为进阶阅读
