Wi-Fi
NoovexOS detects the hardware. It maps the Intel adapter's BAR0, runs the CSR software reset, does the clock handshake, reads the RF-kill switch state and pulls the MAC address out of the chip's OTP registers. All of that is real, correct, pre-firmware bring-up.
And then it stops, because the next step is uploading a 1-2MB proprietary firmware blob into the chip — larger than this entire operating system — after which you'd need the undocumented command interface to drive it, which took Linux years and fifty thousand lines. Scanning for networks is itself a firmware command. The host CPU doesn't tune the radio; it asks the firmware to.
GPU acceleration
NVIDIA's firmware is cryptographically signed and megabytes wide. The framebuffer is the right answer and it's the answer being used.
One ISO for everything
Currently three images ship: ISO for optical and VM, a raw USB image for BIOS machines, and a UEFI image. Collapsing them is blocked by something specific — the boot sector reads stage-2 from LBA 1-4 and the kernel from LBA 5+, as fixed absolute sectors. That works on the USB image, where the boot content starts at sector zero. It cannot work on an ISO, where LBA 1-15 must be the ISO9660 system area and LBA 16+ the volume descriptors.
A true isohybrid needs the boot sector rewritten to be partition-relative. That's a known, bounded piece of work — it just hasn't been done.
