Much thanks to Andre Eisenbach for suggesting that
my kernel needed to be recompiled in order to get the
CD-reader on my SONY VAIO SR27K to work. While I have
not gotten success, I have gotten closer.
I compiled my kernel so that CONFIG_BLK_DEV_IDECS is set
as suggested on the "PCMCIA in the 2.4 kernel series"
web page. (I also found the command 'lilo -v' to be
helpful in tracking down lilo problems.)
Now when I boot, the bootmessages include
: cardmgr[229]: socket 0: Ninja ATA
: kernel: cs: memory probe 0xa0000000-0xa0ffffff: clean.
: kernel: hde: TOSHIBA CD-ROM XM-7002Bc, ATAPI CD/DVD-ROM drive
: kernel: ide2 at 0x180-0x187,0x386 on irq 3
: kernel: hde: ATAPI 16X CD-ROM drive, 128kB Cache
: kernel: Uniform CD-ROM driver Revision: 3.12
: cardmgr[229]: executing: './ide start hde'
: kernel: ide_cs: hde: Vcc = 5.0, Vpp = 0.0
: kernel: hde: command error: status=0x51 { DriveReady SeekComplete Error }
: kernel: hde: command error: error=0x51
: kernel: end_request: I/O error, dev 21:00 (hde), sector 132
: kernel: isofs_read_super: bread failed, dev=21:00, iso_blknum=33, block=66
I then insert the PCMCA card for the CD-ROM and get
: cardmgr[229]: socket 0: Ninja ATA
: kernel: hde: TOSHIBA CD-ROM XM-7002Bc, ATAPI CD/DVD-ROM drive
: kernel: ide2 at 0x180-0x187,0x386 on irq 3
: kernel: hde: ATAPI 16X CD-ROM drive, 128kB Cache
: cardmgr[229]: executing: './ide start hde'
: kernel: ide_cs: hde: Vcc = 5.0, Vpp = 0.0
and when I run 'mount /cdrom' I get
: kernel: hde: command error: status=0x51 { DriveReady SeekComplete Error }
: kernel: hde: command error: error=0x51
: kernel: end_request: I/O error, dev 21:00 (hde), sector 132
: kernel: isofs_read_super: bread failed, dev=21:00, iso_blknum=33, block=66
: mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
: or too many mounted file systems
In my fstab I have
: /dev/cdrom /cdrom iso9660 defaults,ro,user,noauto 0 0
I know that the CD-reader and the CD are good, as I can use
them on the Windows side of my machine.
Anyone have any ideas what I do next?

Can you tell me what kernel option (in .config) this is?

I do not see anything.
root# depmod -a
