this line appears in the kernel log after the "Power on..." line:
ISO 9660 Extensions: RRIP_1991A
seems that it recognized the CD _somehow_ but did not get over the init.

The cable supposed to be good (the machine run on 2.0.3x for months).
Last dev kernel I tried was around 2.1.96 or so, it worked. If you
need it I could revert to 116 but only if you ask for it because the
machine is slow and I am usually not there (hard to arrange).

controller, card, cd, etc:

PIIX: IDE controller on PCI bus 00 dev 38
PIIX: not 100% native mode: will probe irqs later
PIIX: neither IDE port enabled (BIOS)
PIIX: IDE controller on PCI bus 00 dev 39
PIIX: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x3000-0x3007, BIOS settings: hda:pio, hdb:pio
ide1: BM-DMA at 0x3008-0x300f, BIOS settings: hdc:pio, hdd:pio
hda: QUANTUM LIGHTNING 730A, ATA DISK drive
hdc: IBM-DJAA-31080, ATA DISK drive
hdd: PCA123CD, ATAPI CDROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15

The CD is a "noname" 8x ATAPI piece-o-junk.

bye,
