apio	d69e75eb5a	kernel+init: Create a device node in /dev to access the CDROM from userspace! ... Still using PIO, though.	2023-06-03 21:02:37 +02:00
apio	1b141da3a2	kernel/ATA: Read the CDROM's first sector using ATAPI PIO!! ... Sadly, for some reason, DMA is not working right now. This is a problem, as PIO is inconvenient. But hey, it works for now!	2023-06-03 21:02:36 +02:00
