Virgil Dupras	5705cd5c31	Extract EXIT code from stable ABI zone	vor 4 Jahren
Virgil Dupras	4a91ee5c9c	Extract (s) code from stable ABI zone Only its jump addr remains.	vor 4 Jahren
Virgil Dupras	3068b58be5	Rename RAMSTART to SYSVARS It's more descriptive this way. Also, I'll soon add a new HERESTART config.	vor 4 Jahren
Virgil Dupras	94ed01086a	pcat: move drivers and xcomp to blkfs	vor 4 Jahren
Virgil Dupras	d7f002df98	pcat: use boot drive no passed to bootloader through DL instead of hardcoded drive 0.	vor 4 Jahren
Virgil Dupras	cd514e6cd6	pcat: add PSP checks in all native words Also, fix (roll) which wasn't properly implemented.	vor 4 Jahren
Virgil Dupras	1b5333d0b4	pcat: move all find code in _find word It isn't used by low level boot code anymore, so it can go there.	vor 4 Jahren
Virgil Dupras	8cc8df0446	pcat: add native _find	vor 4 Jahren
Virgil Dupras	bd508daad9	pcat: begin organizing native words properly This port is taking shape!	vor 4 Jahren
Virgil Dupras	eed817b517	pcat: adapt to word type change	vor 4 Jahren
Virgil Dupras	16d6a0b377	pcat: begin implementing compiledWord/next	vor 4 Jahren
Virgil Dupras	d8d2e05eb2	pcat: make find compare strings find is the biggest chunk of logic of the boot code. The 8086 version is significantly terser than the z80 one. REP/CMPS helps...	vor 4 Jahren
Virgil Dupras	3be30e24bb	pcat: implement execute and nativeWord	vor 4 Jahren
Virgil Dupras	a72322df31	pcat: begin structuring around words	vor 4 Jahren
Virgil Dupras	2b7abf802f	pcat: begin porting forth I'm not sure yet where I'm going, but I'm not going to build the 8086 port from the ground up like I did with the z80, that is, making is sustain itself and eventually merge its forth code with core words. That would be too much work which would then be thrown out (all those words I'll initially have to implement in asm which are already implemented in Forth). What I think I can do is build a mirror version of z80 boot code and cross-compile it from the z80. This means it has to follow z80 stable ABI. Nope, I'm not sure where I'm going...	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	507c2c12e7	8086asm: clarify operands and fix stupidities	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
