SUMMARY:
The libata=1 option is if you use "AUTO" in the bios, then it sees it but you can't (or I couldn't do anything with it anyway)
scsi1 : ata_piix Vendor: _NEC Model: DVD_RW ND-3520A Rev: 1.04 Type: CD-ROM ANSI SCSI revision: 05
I googled around and then found setting it to Enhanced Mode worked! It sees all the devices properly now.
hdc: _NEC DVD_RW ND-3520A, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15
