catnikita255: I think your ACPI enabling code has some bug, because in Bochs, QEMU, VirtualBox and VMware, the BIOS doesn't enable ACPI for you.
To check if ACPI is enabled, read a 16-bit word from the pm1a_control_block I/O port specified by the FADT, and check if bit 0 (value 1) is set.

I've been implementing "views", to support switching between different consoles. Works fine, except for the scrolling code...

My OS did the same thing my old WinXP PC used to do, lol. :D
I don't know why, but it does this when I run QEMU with "-vga cirrus".
EDIT: Turned out to be a bug in clear_screen in 24-bit VESA modes, and "-vga cirrus" made it use 24-bit VESA.

Looks like I've managed to get the time function to start trying to print out perl scripts out of desperation.

Hi,


I'm doing a rewrite having the old code simply as a pattern. A typo created this starfield.

Hey, if you need a test file and don't want to use the Lorem Ipsum, why not steal the opening of a classic of modern English literature? I'm not sure why Peter chose that particular book, though, but I assume either there were personal reasons or it just happened to be on hand.

Remember, citizen, The Computer... I mean, Big Brother is watching you.

This isn't been critic or something, I've just surprised.
