Setting up IDE CD-ROM on HPPA B2000
Hi,
I have seen several postings mentioning about IDE CD-ROM drives crash the
HPPA boxes while running Linux. I myself also encoutered it repeatedly of
late after succesfully trying various ways to go round it. Thanks to Max
Grabert's help, I have now set it up as IDE-SCSI CD-ROM drive and it seems
to be holding steady so far without me having to try some tricks as before.
If you are interested, followings are what I have done to set up the IDE
CD-ROM as IDE-SCSI CD-ROM under the patient guidance of Max Grabert:
1) Run 'make menuconfig' (or equivalent), select 'Device drivers ->
ATA/ATAPI/MFM/RLL support -> SCSI emulation support' to compile as module
(or into kernel if you prefer);
2) In the same 'make menuconfig' (or equivalent), deselect 'Device drivers
-> ATA/ATAPI/MFM/RLL support -> Include IDE/ATAPI CDROM support' if it is
selected;
3) In the same 'make menuconfig' (or equivalent), make sure that required
CD-ROM file systems are selected under the 'File Systems',
4) Edit palo config file '/etc/palo.conf' to add 'hda=ide-scsi' at the end
of the command line entry (the 1st entry);
5) Recompiled the kernel;
6) Run /sbin/palo;
7) If you compile any of the the above drivers as modules, please make sure
they are also loaded on boot by adding the following lines into /etc/modules:
iso9660
udf
ns87415
ide-scsi
sg
sr_mod
8) Reboot.
Remember from now on your IDE CD-ROM drive will be known as /dev/scdX.
/dev/scd0 in my case.
Rgds,

ps. Any downside in setting up IDE CD-ROM as IDE-SCSI CD-ROM?
pps. You might see the following msg but I believe it is harmless:
modprobe -k ide-mod options="hda=ide-scsi"
FATAL: Module ide_mod not found.
pps. You might also see the following msg: (Does 'deprecated for cd
burning' msg mean that we can burn CDs if we have a CD/RW drive?)
ide-scsi is deprecated for cd burning! Use ide-cd and give dev=/dev/hdX as
