It’s just the latest twist in the acquisition saga, which started with a bidding war that reportedly also involved Apple, Amazon, and Comcast. Once Netflix and Warner Bros. came to an agreement on December 5th, Paramount tried to force its way into the deal, announcing a hostile bid worth $108.4 billion in cash. Unlike Netflix’s deal, Paramount’s includes an acquisition of all of Warner Bros. Discovery, including its cable networks.
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.
