Simple, kernel-only, 64bit OS, early stage. https://git.2137697.xyz/rs-dos/atom?h=qemu 2026-08-21T17:13:52Z 2026-08-21T17:13:52Z salmonik salmonik@tuta.io 2026-08-21T17:13:52Z urn:sha1:298528581d1a29032a1224600297316384d4e4f7 mksystem.sh stages one FAT32 image: \bzImage + \initramfs.cpio.gz (rsbl paths), \EFI\BOOT\BOOTX64.EFI (kernel direct by default, --chain for rsboot), \etc\motd.txt, empty \bin\cli + \bin\gui, seed files at the root. --gpt wraps it in a partition table for real USB dd targets. Makefile: run/run-gui/debug attach only system.img on ide.0 (vvfat lines deleted); stamp-based 'system' target rebuilds only when the kernel is newer, so runtime writes survive reboots; system-fresh wipes; inspect lists via mtools. build-image.sh/mkdisk.sh removed. test-disk.sh boots system.img with a throwaway OVMF varstore — a stale NvVars makes the firmware skip the \EFI\BOOT fallback. sendkeys.py pacing 50ms->250ms/1.5s: keystroke loss under host load corrupted typed lines (guest-side PS/2 ring overflow). Gate: test-disk PASS (fsck clean, file survives poweroff). 2026-07-31T01:22:20Z salmonik salmonik@tuta.io 2026-07-31T01:22:20Z urn:sha1:0ace22d6f88692883584119c64ff010f4cee6738
