Testing told me I used ~3,500 bytes for each frame - at 10 FPS, that’s ~35 KB/sec. While a nice T1 line could handle that, it’d easily saturate a 56k modem. And supporting even 1,000 clients would mean pushing 35 megabytes a second - way too much!
When VM=1, the protected-mode bit goes low and the Entry PLA selects real-mode entry points -- MOV ES, reg takes the one-line path. Meanwhile, CPL is hardwired to 3 whenever VM=1, so the V86 task always runs at the lowest privilege level, under full paging protection. The OS can use paging to virtualize the 8086's 1 MB address space, even simulating A20 address line wraparound by mapping pages to the same physical frames.，这一点在夫子中也有详细论述
