Hi all! It's me again ;))) So, I want to share subj. How do you think a shadow person determines What page does it launch from? Elementary: into the page that is installed updated when the shadow site was launched, at #C001 (49153) 2 bytes are written: 85 (#55) and 170 (#AA). Otherwise, number #AA55. Later the shadow starts to spin pages, starting from zero, until address #C001 will not detect the above-mentioned those bytes. Hence the conclusion: shadow business is possible deceive - write to the page with the number rum below working number #AA55 in #C001. And the shadow guy will show you the wrong page! In addition, it will return to that page which he defined (incorrectly). As a way protection is unlikely to be used, but if you ever have a glitch RST 8, see if you have #AA55 at #C001. Although the likelihood of this small, but you never know... In general, digging into the ROM of the shadow worker gave information interesting results... So, everyone knows We have subroutines #81 (BIOS), #89 (CMOS), #87 and #88 (Turbo), and #85 (shadow cut) ka). But it turns out that there is also a bunch undescribed RST 8! Yes, people are absolutely I accidentally found out that #8B runs files, discarded by alternative Magic... Also, #8D does something with disk house (not just spins it!), but #8C generally throws it into the buffer (specified in Hl or DE) BASIC!!! ;) People, if you know anything about special Benefits of Shadow Shadow Programmingscorpion, please share with us! ;) Best regards, Vega from Style Group. -+- Basic 48.
