tautvilas / eveos Goto Github PK

When running EveOS in BOCHS system clock seems to be running too fast. It
might be that the problem is in timer_set_rate function.

Uzkroviau savo sourca i svn. Any comments? Jei viska sukompiliuosi
tvarkingai ir paleisi ekrave turetum matyt kazka panasaus i ta piesinuka,
kuri prisegiau.

P. S. Sauktukas tai savotiska debug info kad branduolys jau veiksnus ir
bendrauja su pasauliu:)

Taigi taigi. Atejo laikas daryti GDT:)

Reiktu nuspresti ar GDT darom su pliku assembleriu ar su C & asm. As uz
plika ASM.

Beje speju i video atminti man butent del to ir neraso nes nesutvarkytas
GDT. Nes tame kernelio pavyzdyje tai grubas jau sutvarko GDT kazkokia forma
kad atmintim butu galima naudotis. O jei tiesiog pereini i 32 bit tai su
atmintim buna visiska fignia:)

When TAB is printed cursor is moved to the right to make tabulation as
expected. Then if BACKSPACE is printed the cursor is moved only one
position to the left while it is expected to remove all output done by TAB.

This problem exists because VGA does not check what is printed on screen
before the cursor position when handling BACKSPACE. Actually VGA has no
text buffer what was printed on screen except of that text that are in VGA
memory it self. Because TAB is handled by printing needed number of SPACEs
instead of actual TAB symbol it is imposable to tell if the TAB or actual
SPACE was printed and it imposable to know how many symbols to remove from
screen.

That wouldn't be that bad but when entering text from keyboard and trying
to BACKSPACE TABs keyboard buffer looses synchronisation with screen.
