Complete overhaul of recipes Recipes contain bits and pieces of hardware-related knowledge, but these bits feel sparse. I've been wanting to consolidate hardware- related documentation for a while, but always fell at odds with the recipes organisation. We don't have recipes anymore, just a /doc/hw section that contains hardware-related documentation which often translate to precise instructions to run Collapse OS on a specific machine. With this new organisation, I hope to end up with a better, more solid documentation. 2020-10-31 11:31:47 +11:00			`# See /doc/hw/8086/pcat.txt`
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. 2020-06-14 05:35:16 +10:00			`TARGET = disk.bin`

Add words \|M and \|L Splitting a word into MSB/LSB pairs happens often and is worth, I think, native words. Also, I'm going to need it in the upcoming commits. 2020-12-08 12:08:45 +11:00			`blkfs: $(BLKPACK) blk.fs`
Transform "blk/" folders into "blk.fs" text files Working in "blk/" folder from a modern system is harder than it should be. Moving blocks around is a bit awkward, grepping is a bit less convenient than it could be, git blame has troubles following, etc. In this commit, we modify blkpack and blkunpack to work with single text files with blocks being separated by a special markup. I think this will make the code significantly more convenient to work into. 2020-11-15 10:00:31 +11:00			`cat $(BASE)/blk.fs blk.fs \| $(BLKPACK) > $@`

Move 8086 assembler from B730 to B30 Also, move doc to doc/asm.txt. Also, fix the pcat recipe which was broken since the overlay change. I hadn't noticed it because I didn't have to rebuild the MBR. 2020-09-22 09:23:33 +10:00			`mbr.bin: mbr.fs $(STAGE) blkfs`
