Long ago we had an exchange about what was happening for sc for 13. I'd provided some notes about contexts in which vt or sc did not work in my environment. I've rechecked some contexts and found that for: # ~/fbsd-based-on-what-freebsd-main.sh mm-src 818390ce0ca539300dd15d7a817784f1e3f7a9b8 CommitDate: 2021-01-13 14:54:46 -0800 4180404713ec 818390ce0ca5 (HEAD -> mm-src) mm-src snapshot for mm's = patched build in git context. (I run with patches to work around various FreeBSD problems with handling old PowerMacs. That is why it is not just 818390ce0ca5.) PowerMac7,2 G5: vt works, sc hangs just after "Kernel entry at 0x100580 = ...". iMac G3 (PowerMac4,1): sc works, vt fails (showing a blank screen). (These are basic console-display tests, not validation that most = everything displayed well.) Unfortunately the old 2-socket-/2-cores-each G5 with the Radeon X1950 suffered heat-death (CPU cooling failure). It used to be that vt mishandled a 2560x1440 display for this context and caused a boot-crash. I used to have to use sc instead to use that display. (I do still have access to the video card but it is not in any machine.) I can say that, on the GeForce 7800 GT based 2-socket-/2-cores-each G5, vt works with that same display. sc does not display fancy open/close double quotes correctly in man output: a sequence of odd symbols = instead. But its basics were working, using somewhat less of the display area. The other PowerMac contexts that I can still readily test still basically work for both vt and sc booting. None of my activity attempts to get X going: just console display. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
