ide device error

Post by dwe.. » Sat, 26 Sep 1998 04:00:00



My CD-ROM (Samsung 32X SC3230) is not recognized by Linux but
is recognized by many commercial ATAPI drivers for the
Dos/Windows world. I get the following as shown by dmesg:

PIIX4: IDE controller on PCI bus 00 dev 09
PIIX4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA, hdb:DMA
    ide1: BM-DMA at 0xe008-0xe00f, BIOS settings: hdc:DMA, hdd:pio
hda: Maxtor 87000D8, ATA DISK drive
hdb: Maxtor 90432D3, ATA DISK drive
hdc: no response (status = 0xd0)
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: Maxtor 87000D8, 6679MB w/256kB Cache, CHS=851/255/63, UDMA
hdb: Maxtor 90432D3, 4121MB w/256kB Cache, CHS=525/255/63, UDMA

I don't know but it is strange that the hdc is recognized as DMA
when it is really PIO.

first, did you compile IDE/ATAPI CD-ROM support into the kernel?i don't
know whether it is the default or not. it's under the block devices
section if you do make menuconfig.

i think each ide controller can support two devices only: 1 master, 1
slave.you seem to have two controllers, ide0 and ide1. am i right that
you have
three disks in the system? two are on ide0, and one is on ide1 together
with
the CD-ROM?

if so, then i think my original suggestion may be right and you don't
have
the proper driver compiled into the kernel. that could explain why hdc
and hdd are not recognised correctly.

Good Luck!

Try setting it to lower pio mode in bios setup. This sometimes helps to
detect otherwise nondetected cdroms.
