💀 BUGS 💀

okay so this is the serious part, bestie — read it twice:

This device requires IRQ 9 exclusively. To use this, you should enable ACPI function in BIOS configuration, or PnP mechanism assigns conflicted IRQ for PnP ISA card. And do not use IRQ 9 for Non-PnP ISA cards.

like, fr fr, IRQ 9 is not sharing. respect the exclusive main character energy of this device, no cap 😭
