| * | snapshot: write to disk using BIOS | Kartik K. Agaram | 2021-03-15 | 1 | -0/+14 |
| | | | | | | | | | | | Requires the following commands: dd if=/dev/zero of=data.img count=20160 ./translate life.mu qemu-system-i386 -hda disk.img -hdb data.img Before running Qemu, data.img will contain all 0s. After quitting Qemu, data.img will contain the first 512 bytes of disk.img. | ||||

| * | fix a benign bug so far | Kartik K. Agaram | 2021-03-14 | 1 | -16/+16 |
| | | | | | | | | | | I'd been assuming that the image would be identical if it worked, but I need to actually validate this at each step: ./translate life.mu && qemu-system-i386 disk.img && diff disk.img 0 The plan is to keep the binary identical until I finish translating boot.subx. Then I can remove obsolete padding. | ||||

| * | start converting boot.subx to real SubX | Kartik K. Agaram | 2021-03-14 | 1 | -35/+11 |
| | | | | | | | | | Just one instruction translated so far. The rest is treated as data. Currently programs only work because the toolchain treats boot.subx as all data. As we turn it into code we'll move the '== data' segment boundary further down. | ||||
