When your OS goes crazy - Screenshots

Finally I can show something crazy
I messed my terminal some way.
"[ERROR] CPU Exceptionized. Loading the shell."

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 know.

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.
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.

I guess the stack corrupted

I suppose it is the screensaver?

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.

Code: Select all

size_t index = y * index + x;

should be

Code: Select all

size_t index = y * width + x;

Changed character width.

Two bugs at once: unexpected end of file when reading ELF file and scrolling bug. "EyePet"? Wut?

How crazy is that - a 1.44MB FAT32 floppy disk

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.
