ORM(4)

💅 ORM(4) — the ISA option ROM driver, bestie

okay so real talk, this one's from the Kernel Interfaces Manual, and it's short but it's iconic. let's get into it 🫶

---

✨ NAME ✨

orm — the ISA I/O space option ROM(s) driver. that's it, that's the whole vibe. she scans, she claims, she slays 💅

---

🌸 SYNOPSIS 🌸

orm is automatically included on all systems that have an ISA bus.

no cap, you don't even have to do anything. if your box has an ISA bus, orm is already there. main character energy fr — she just shows up ✨

---

🦋 DESCRIPTION 🦋

okay so here's the whole lore: at boot time, the driver scans the ISA I/O memory space looking for option ROM(s) 👀 and then it claims them. periodt.

and like… that claiming thing actually matters, because it means other drivers are precluded from using ISA I/O memory that sits on top of an option ROM. she called dibs. respectfully 💖

tl;dr — she scans, she claims, everybody else can go find their own memory. iykyk 🧚

💀 BUGS 💀

okay so this is the messy part, and we're not gonna pretend it isn't 🙈

due to the implementation of the resource manager, other drivers cannot attach to the option ROM address range.

not me reading this like three times 😭 that's literally just how it is — it's a real limitation, not a you problem. lowkey unfortunate but we move 💅
