Having these two cd tapes and the obvious hard disk, how do I interface
these ide devices in the two ide-ports of my computer? I mean there is
some alternative clearly better such as hard disk (hda), cd-rom(hdb),
and cd-writer (hdc), or the other way around, there is some
configuration that could create problems such as hard disk (hda),
cd-rom(hdc), and cd-writer (hdd)
I have read two web pages on the net with different approaches for the
configuration of both cd-drives: one (
http://www.linux.org/help/ldp/howto/CD-Writing-HOWTO.html ) lets the
cd-rom working as an ide drive and the cd-writer as a scsi drive; in the
other page ( http://buberel.org/linux/cdrw.php ) both are configured as
scsi drives...is one configuration better than the other one?
In a third web page (
) I read something that I didn't read in the aforementioned ones about
modifying the ide.h file in the /usr/src/linux/drivers/block directory
as follows: change this line #define WAIT_CMD (10*HZ) /*
10sec - maximum wait for an IRQ to happen */, to the following
line #define WAIT_CMD (1000*HZ) /* 1000sec - maximum
wait for an IRQ to happen */ in order to get the software cd-record
working properly....should I do this change?
About the kernel o module support for IDE/ATAPI CD-ROM, I have read both
ways: keep it and disable it. Moreover, I have found no logic for this
kernel configuration option base on the reading of the three mentioned
papers....so, what do I do? when should I have IDE/ATAPI CD-ROM support,
and when should I disable it? WHERE IS THE LOGIC?
PS I have a mandrake 7.1 distribution with the 2.2.14 kernel.
