Reference analysis for Red Bear OS integration based on running the
latest CachyOS desktop ISO (28 Jun 2026) under QEMU/KVM. Documents
the hardware-enumeration and kernel-init sequences a reference Linux
distro produces on the i440FX + PIIX machine type that Red Bear OS
also targets, with line-by-line mapping to Red Bear OS subsystems
(pcid, ided, e1000d, vesad, xhcid, hwd/acpid).
- local/docs/CACHYOS-INTEGRATION.md: Cross-cutting analysis
(executive summary, hardware inventory, ACPI table coverage,
PCI quirks, boot-phase ordering, init system comparison, action
items).
- local/docs/boot-logs/cachyos-kernel-20260629-0520.log: Captured
441-line dmesg-grade log from the CachyOS kernel boot (SeaBIOS
handover through ACPI, PCI, USB, ATA, network enumeration and
up to a rootfs shell prompt).
- local/docs/boot-logs/cachyos-boot-20260629-0520.md: Pointer
document with the capture command and the rationale for the
indirect-kernel invocation (the QEMU + CachyOS + KVM boot stalled
at the ISOLINUX EDD probe when run from CD; bypassing with
-kernel/-initrd and an explicit console=ttyS0 earlyprintk command
line recovered the full log).
