Implement ATAPI_CMD_READ_DISC_STRUCTURE #7

Open aperezbios opened 1 year ago

aperezbios commented 1 year ago

When attached to my beige PowerMac G3, upon a simple boot (not from CD) I observed the following:


[95813ms] DBG -- ATAPI command: ATAPI_CMD_READ_DISC_STRUCTURE 0xAD 0x00 0x00 0x00 0x00 0x00 0x00 0x01 0x00 0x08 0x00 0x00

I haven't actually implemented this command.

But it seems to be DVD-specific, maybe with some of the other changes the computer now realizes that medium type is CD, not DVD.

Got it. Well, support for basic DVD-ROM functionality is something I want to eventually get to, so I'll leave this open for now.
