apio	67e8a2dd4b	kernel: Do not automatically read the MBR partition table from /dev/cdrom ... Since ff952cfe16 made /dev mounted from userspace, /dev/cdrom does not exist when ATA drives are scanned.	2023-06-04 11:14:04 +02:00

apio	cf549b41ea	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!	2023-06-04 11:14:03 +02:00
