Dual Boot with RAID and Two Hard Drives

Ok Here is my question:

I Wanted to dual boot windows XP and Linux Mandrake 9.0. I buaght a Brand new hard drive for doing this because I heard about all the horror stories of deleating partitions and loosing data. My Windows XP partition (NTFS) is on a PCI RAID card (acard ultra ATA 133 PCI Raid) when I went to install linux LILO couldn't find my hard drive on the RAID card. I reinstalled Linux but no luck. My computer booted to linux fine but now I can't get into XP without cutting the power from the Linux hard drive. When I went to edit LILO from Mandrake I still didn't find my Raided hard drives. I've read some posts on linux dual boot with two hard drives and some on booting with a RAID config. but none dealing with both. Is this even possible I would like to keep my windows partition and not have to back it up since I am a Student recording engineer and I have many files that should not be compressed (use lossey compression) to back them up.

Here is a Copy of my lilo.config:

boot=/dev/hda
map=/boot/map
default=linux-smp
keytable=/boot/us.klt
prompt
nowarn
timeout=100
message=/boot/message
menu-scheme=wb:bw:wb:bw

initrd=/boot/initrd.img
append="devfs=mount hdd=ide-scsi quiet"
vga=791
read-only
image=/boot/vmlinuz
label=linux-nonfb
root=/dev/hda1
initrd=/boot/initrd.img
append="devfs=mount hdd=ide-scsi"
read-only
image=/boot/vmlinuz-smp

initrd=/boot/initrd.img
append="devfs=nomount hdd=ide-scsi failsafe"

Any help would be Great.

Thanks,
James

No Replies still after a week. Does anyone have any info on my problem? Anyone?

Ok James,
I need some more info.

According to your lilo.conf your default boot is linux-smp, do you have two CPU's and if so what are they and what motherboard are they on?

Do "lspci -vv" and post all the information about the PCI RAID card.

Do "fdisk -l" and post the output.

Post your /etc/fstab.

Yes I am running a dual proc system 2 AMD 1800 mp's on a Tyan Tiger MPX Mobo.

I think this is my info on the PCI Raid card but maybe not:

Hope this helps thanks for everything so far.

The RAID card seems to be the problem, you say it's an ATA133 card in your first post but according to the output of lspci you have a SCSI card?

Quote:

00:09.0 SCSI storage controller: Artop Electronic Corp ATP865 (rev 02)
Subsystem: Artop Electronic Corp ATP865

We need to determine the truth here as a scsi drive will have a different /dev name to an ide drive.

Maybe your right on the windows XP device manager it says my device is "acard raid 0 hd0 SCSI Disk Device" Hope this Helps

Okay here's the deal in mandrake my device is listed as a SCSI controller, but when I went to try to find a driver for the model (acard ATP-865) it is listed as an IDE Device here's the site I went to

Click Here

Ok, I found an option in the kernel for Artop support (file:/usr/src/linux-2.4.20/drivers/ide/aec62xx.c), but I don't know if your chip is supported yet, check your kernel .config file for the following, CONFIG_BLK_DEV_AEC62XX=y, if it's not set then that maybe why it's not working, if it is set then support for this chip has to be added to the kernel.

What Directory would the kernel .config file be in I can't find it in the usr/source directory, however I did find the aec62xxx.c in the dir you mentioned. Do I need to recompile the kernel if I don't find it?

James

The . before .config means that it's a hidden file and you can usually find it in the top level of the kernel source, it might be in your /boot directory without the dot though, if it is it will have a similar name to your kernel. Look for a text file that starts like the folowing,

Code:

#

# Automatically generated by make menuconfig: don't edit

#

CONFIG_X86=y

# CONFIG_SBUS is not set

CONFIG_UID16=y



#

# Code maturity level options

#

CONFIG_EXPERIMENTAL=y



#

# Loadable module support

#

CONFIG_MODULES=y

# CONFIG_MODVERSIONS is not set

CONFIG_KMOD=y

I found the file here are the sections that I thought it might be in:
#
# Block devices
#
CONFIG_BLK_DEV_FD=m
CONFIG_BLK_DEV_XD=m
CONFIG_PARIDE=m
CONFIG_PARIDE_PARPORT=m

#
# Multi-device support (RAID and LVM)
#
CONFIG_MD=y
CONFIG_BLK_DEV_MD=y
CONFIG_MD_LINEAR=m
CONFIG_MD_RAID0=m
CONFIG_MD_RAID1=m
CONFIG_MD_RAID5=m
CONFIG_MD_MULTIPATH=m
CONFIG_BLK_DEV_LVM=m

No luck though as you can see CONFIG_BLK_DEV_AEC62XX=y is missing.

Whats Next?

Dual Boot with Windows and Linux

First, I am a Linux Newbie so if I am not even up to speed enough to appreciate the true problem please excuse my ignorance.

I just created a dual boot, dual ATA hardrive situation with Win2K and Red Hat Linux. I did alot of reading first and used these sites to set it up. Now it works clean. This entails using the Windows boot loader to load either.

Because you get Linux and not Windows is that the Master Boot Record for Windows got messed up when you installed Linux which is easy to do during the LILO installation if you install it on the MBR instead of a superpartition on your Linux drive. The sites below tell you how to fix it and how to get it working if that is your problem.

http://www.anandtech.com/guides/viewfaq.html?i=58

http://support.microsoft.com/default...b;en-us;311578

Again, if I am in the dark I apologize.

JZ

Do "cat /usr/src/linux/.config | grep AEC62XX", this is what mine outputs,

Code:

bern@grendel bern$ cat /usr/src/linux/.config | grep AEC62XX

# CONFIG_BLK_DEV_AEC62XX is not set

# CONFIG_AEC62XX_TUNING is not set

Here it is:

[moephish@d172-16-74-114 moephish]$ cat /usr/src/linux/.config | grep AEC62XX
CONFIG_BLK_DEV_AEC62XX=y
CONFIG_AEC62XX_TUNING=y

It says that aec62xx is there funny?

OK, the next step involves building a custom kernel, if you want to take it that far.
Here is some reading matter while you decide,
