Virgil Dupras	3b21ba635d	pcat: add PICK and (roll)	vor 4 Jahren
Virgil Dupras	a92864a595	pcat: implement RSP mechanism in execution model	vor 4 Jahren
Virgil Dupras	8c452f5add	pcat: begin implementing find Not comparing strings yet. Without asm tooling support, it's a big chunk to swallow at once. It's progressing well!	vor 4 Jahren
Virgil Dupras	3be30e24bb	pcat: implement execute and nativeWord	vor 4 Jahren
Virgil Dupras	bf0e999f8e	pcat: read LATEST and jump to it	vor 4 Jahren
Virgil Dupras	a72322df31	pcat: begin structuring around words	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	b037c86598	recipes/pcat: now tested on real hardware!	vor 4 Jahren
Virgil Dupras	66b27b0790	8086asm: properly initialize DS and DF	vor 4 Jahren
Virgil Dupras	4e18fafe46	8086asm: now enough tooling to assemble a PC/AT Hello World boot	vor 4 Jahren

Virgil Dupras	749fdf1b18	8086asm: add 8-bit JMP, MOVrI, INT, Verified against nasm with equivalent code.	vor 4 Jahren
