Linux allows you to have as many as 10 IDE controllers. On the IBM PC
architecture, you will run out of IRQs before you can squeeze that many
in.
Older PCs came with only one IDE controller, which always occupied IRQ
14. Newer ones have 2, on IRQ 14 and IRQ 15. If you really need more,
you can buy add-on cards like Promise's HPT366 which have two IDE
controllers attached. Using the HPT366 can be a bit of a pain under
Linux *if* you put /boot on a drive that's hooked to the HPT366--search
this NG for details and complaints, but once it's working, it works
fairly well.
Also, for the best performance in I/O, forget the Promise card and buy a
SCSI card. 7 devices, one IRQ, less CPU required, no need to fiddle
with DMA settings. It's more expensive but well worth it if you're
concerned about performance and expandability.

Don't forget damn slow on recovery. If you can afford to be without your system
for a WHOLE DAY waiting for the piddling recovery speed, have a ball. A friend
found this out the hard way. If this is for a personal system, fine.
I recommend you look into CD-RW drives. The media is cheap and they work out of
the box... mostly. Go for a SCSI CD-RW; IDE support under Linux mostly works.

one thing I tried before was to use a old ide drive udma33 as root
partition and also as /usr. However once I installed the system I moved
all the large programs that will benefit from fast disk access like
netscape and staroffice to new udma66 drive which I mounted as
/usr-mirror and linked the sites back to /usr for faster load times.
Anyway I had quite a problem with onboard hpt366 on the abit bp dual
celeron 433. So I am not sure if it is worth all the trouble atm. Wait
till 2.4 was my idea. It was losing interrupt and waits eternally
causing kernel to lock up.

Subject: IDE CD-RW doesn't work after RedHat 6.2 upgrade
Date: Sat, 29 Jul 2000 12:25:44 -0700
I HAD my IDE CD-ROM working with RedHat 6.1 using the stock 2.2.12
kernel, following the instructions in the HOWTO for these devices. I
can't figure out now how to make it work for the life of me after
upgrading to RedHat 6.2.
First: I'm running a SoundBlaster MK4214 CD-RW drive. I would like to
emphasize it WAS working with RH 6.1.
I first backed up my old 6.1 system onto CD-R's. Then, because my
partitions were screwy (I built a classic Unix / and /usr rather than a
/boot and /, which makes more sense for RedHat), I wiped out the old
install and partitions and built a clean installation of RedHat 6.2. I
then followed the instructions for building the kernel modules, and set
the listed modules as follows (y = built-in to the kernel, m = module):
BLOCK Enhanced IDE/MFM/RLL... Y
BLOCK IDE/ATAPI CDROM ide-cd M
BLOCK SCSI emulation support ide-scsi M
BLOCK Loopback device loop M
SCSI SCSI support scsi_mod Y
SCSI SCSI CD-ROM support sr_mod Y
SCSI Enable vendor-specific Y
SCSI SCSI generic support sg Y
I'm using the Adaptec 1542 support for the generic driver. I did the
usual kernel stuff
make dep
make clean
make dep
make bzImage
make modules
make modules_install
cp arch/i386/boot/bzImage /boot/vmlinuz-smp2
lilo
My /etc/lilo.conf file looks like this:
=====
boot=/dev/hdc
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
default=linux
image=/boot/vmlinuz-2.2.14-5.0smp
label=linux
read-only
root=/dev/hdc6
image=/boot/vmlinuz-smp2
label=linux-smp2
read-only
root=/dev/hdc6
append="hdb=ide-scsi"
image=/boot/vmlinuz-2.2.14-5.0
label=linux-up
read-only
root=/dev/hdc6

When I boot, the following mess shows up:

?? Three problems here: IDE/ATAPI CD-ROM should be "N", as you're going
to be using the SCSI emulation anyway. Second, ide-scsi, scsi_mod,
sr_mod, and sg should probably all be modules or all be compiled in--
your choice there. Third, if you're using IDE-SCSI emulation, you don't
need any SCSI hostadapter support at all, as the ide-scsi emulation will
be your scsi hostadapter. (Disregard this if you actually have an
Adaptec 1542 card in your system!)
[large snip]
depmod returning so many errors is a bad sign. One thing that I like to
do when messing with new modules is an "rm -rf
/lib/modules/$KERNELVERSION" immediately before doing "make
modules_install ; depmod -a".
Your /etc/conf.modules should contain a line like so:
alias scsi_hostadapter ide-scsi
for reasons outlined above.
>What am I doing wrong here? I have also tried making a new initrd file,

initrd is more trouble than it's worth. The *only* reason that initrd
exists is for installation and rescue purposes; a production system
should never need it. If you have support for ELF binaries, the ext2
filesystem, the VGA or framebuffer console, and the disk your root
filesystem is on (IDE or SCSI disk support) compiled directly into the
kernel, there's no need for initrd.

Hi, and thanks for the advice. The web page
http://www.inria.fr/koala/colas/mouse-wheel-scroll/ was helpful.
I did get this to work, by commenting out the lines in my XF86Config file:
Emulate3Buttons
Emulate3Timeout 50
These interfered with the mouse wheel functionality, and that's
understandable. I didn't need to use middle button emulation of course,
and I don't know why the lines were not commented out in the first place.
Now I just have to get scrolling to work in Netscape (I'll investigate
imwheel), my CD ROM drives to both work, NFS, wine, and Samba. Then, I'll
be very happy!

Hi Folks, I've been told that I'll need Linux on my PC for this years
part of my degree course starting in September. I picked up Mandrake 7.0
on a PC-Plus cover disk and the install seemed a breeze. I gave it a
tough test too as I only allocated it 2Gb in a second logical partition
of my second drive hidden away on the second IDE port. It booted from
the CD, asked me to point at a partition, then got on with the job. It's
all running okay except for a few minor items which I would now like to
fix.
Firstly, I have a PCI modem from Diamond Multimedia which goes by the
name of a Supra Express 56i V Pro. This is a 56K Internal Voice Modem
which supports V90 and on a good day gets me to Demon at 48k using
Windoze98SE. According to system/devices it also contains a Supra 2560
PCI Modem Enumerator. However, when running Linux and using the Mandrake
DrakConf to locate PCI hardware, the details page against the modem
remains blank. I have scanned the "documentation" that came with the
modem and it does NOT say "winmodem" anywhere in the text - is this good
news or a red herring? Has anyone managed to get this modem running
under Linux and if so how?... Please..... I'm getting bored booting into
Windoze every time I need another patch!
Second, Now this really is silly... I have a NEC SuperScript 610plus
laser printer (Yes I know it's GDI design!). I bought it 3 years ago
when it was 200 UKP and a "proper" laser with PostScript was 800 UKP. It
seen me through 4 Windoze upgrades and I still think it's a cute device,
but of course the standard PS or DM drivers won't touch it. Has anyone
done any work on GDI printers under Linux....?
Lastly, I am using a Matrox Millennium II (MGA 200) graphics card (AGP)
in an ASUS P2B MotherBoard. I know that I can display 6 concurrent
Windoze Media Player 7 mpegs tiled on screen and still see all frames
(frame rate drops to 28 fps from 30). Sound is a bit confused though!
However, under Linux I cannot watch one mpeg as the picture is broken up
into rectangles which seem to show bits of different frames overlapping
as it runs. You can make out that the film is about, but it's not very
watch able. Am I expecting too much here, or is there something I could
do to improve performance?
System Hardware:
ASUS P2B (100fsb)
128Mb RAM (PC100)
Celeron 266 (Over Clocked to 400)
Seagate 13Gb Hard Drive
Seagate 5.2Gb Hard Drive
Iomega ZIP
Sony 3.5 Floppy
Sony 40x CDR
Matrox Millennium 2 16Mb
Sound Blaster AWE64 Gold
Sony Multiscan 15sf
Thanks in advance, you can all laugh now....
