Virgil Dupras	d7f002df98	pcat: use boot drive no passed to bootloader through DL instead of hardcoded drive 0.	vor 4 Jahren
Virgil Dupras	dc7f36263a	pcat: BLK-enabled! That INT 13H logic was a bit tricky to implement... read-only for now.	vor 4 Jahren
Virgil Dupras	60ecab314e	pcat: we have PROMPT! Not working, but we do get that sweet "CollapseOS".	vor 4 Jahren
Virgil Dupras	9d2afd200c	pcat: implement (s)	vor 4 Jahren

Virgil Dupras	a92864a595	pcat: implement RSP mechanism in execution model	vor 4 Jahren
Virgil Dupras	dabbd6c253	8086asm: add support for modrm 8-bit displacement	vor 4 Jahren
Virgil Dupras	1a467efae1	pcat: use a far jump to boot into the OS Unless I misunderstood, this is supposed to set CS. This would make all SREG have the same value. This allows us to remove BIN( offset from os.bin. I've tried booting to offset 0, but it didn't seem to work. Let's settle for 0x8000. 512kb of system RAM is way more than we need anyways.	vor 4 Jahren

Virgil Dupras	5033f17be2	8086asm: tidy up a bit	vor 4 Jahren
Virgil Dupras	07e50313c7	pcat: separate MBR code and OS code MBR code now strictly loads OS code into memory and jumps into it. Now, I've got to consolidate my assembler code, modrm logic is messed up.	vor 4 Jahren
Virgil Dupras	e17f2e6907	pcat: read sector from floppy	vor 4 Jahren
Virgil Dupras	b037c86598	recipes/pcat: now tested on real hardware!	vor 4 Jahren
Virgil Dupras	66b27b0790	8086asm: properly initialize DS and DF	vor 4 Jahren
