# Felhom ISO build profile — HP mini (second pilot board, 2026-07-21). # # Same shape as profiles/n100.profile, with ONE deliberate difference: the loader default is left at # the stock signed `shim` chain rather than `mkimage`. # # WHY: `mkimage` exists to work around the N100's early AMI (AN3PLUS-class) firmware, which cannot # USB-boot the ISO's stock signed GRUB (VALIDATION-n100-baremetal F1, `relocation 0x0`). That is a # defect of that firmware, not a Felhom requirement. HP business-desktop firmware is Secure-Boot # capable and generally standards-compliant, so `shim` is the one to try FIRST — it keeps Secure # Boot working, which `mkimage` cannot (it is unsigned; an SB-enforcing board refuses it outright # with "Access Denied" — proven, RUNBOOK-B leg 3). # # The board's firmware is nevertheless UNKNOWN until it is in hand, so BOTH loader variants are # built from this one profile — the AMI lesson is to carry both rather than make one trip: # bash scripts/iso/build-felhom-iso.sh … --profile scripts/iso/profiles/hp.profile --pairing --loader shim # bash scripts/iso/build-felhom-iso.sh … --profile scripts/iso/profiles/hp.profile --pairing --loader mkimage # # ⚠ THIS PROFILE IS DELIBERATELY INERT — it ships the MATCH-NOTHING disk filter as a safety default, # exactly like n100.profile. Built as-is it is the `hp-safety` pre-flight ISO: it boots the full # installer path and then ABORTS having touched no disk (spike S5c). That is the point — the first # thing a brand-new board ever runs should be provably harmless, and it proves the loader + Secure # Boot setting before anything destructive exists on a USB stick. # # To ARM it for the real install, do NOT edit this file: copy it to an UNCOMMITTED working profile # (the n100-demo.profile precedent — a real serial and any baked key must never be committed), # replace the serial below with the target SSD's real ID_SERIAL_SHORT harvested from the board # pre-wipe (`lsblk -o NAME,SERIAL` / `udevadm info`), and rebuild. Confirm the serial is the # INTERNAL SSD and not an attached backup drive — that check is what protected the N100's external # HDD on the rehearsal run. FELHOM_FQDN="felhom-host.local" # Loader: stock signed shim (Secure Boot stays ON). Override per-build with `--loader mkimage` if the # board turns out to have the N100's GRUB relocation defect — and set Secure Boot OFF if you do.
