Booting to Nvidia Raid......HELP pls!

I am starting a new installation on a K8n Neo4 Platinum PCB(1).
I am trying use 2 WD 250 GB Sata 2's as a mirrored boot drive.
I enabled the Nvidia raid in bios, enabled the SATA ports, booted & entered the Nvidia RAID format, set my drives as mirrored & boot. Then rebooted.
I am installing windows 2000 Pro SP4. At the prompt I enter [F6] & installed the supplied diskette. Pressed S when prompted & loaded both drivers. I then get a stop error during windows installation.
Tried again with only 1 driver, same thing, then the other driver, same thing.
The Disc says WINXP so I replaced the HD & went to the internet, DL's the Win 2000 drivers & repeated the installation.
Same thing.
What can I do?

I do have the unused SATA ports turned off.
Will try that when I get home.
Spoke with MSI this moring there response was "DUH?".
Given all the probs with SATA-2 you might want to jumper the drives to SATA-1, at least until the install is done. I'd also run the WD Diags first to make sure the drives are recognized and can be written/read through BIOS.

K8NGM2 Long boot with Nvidia RAID enabled *SOLVED*

Hi,
I just bought the K8NGM2 and first had the engineering bios... i upgraded to version 3.10 without any problems.
After I setup my RAID array The computer will boot, get past the RAID press f10 screen and get stuck at "Checking NVRAM" for about (timed) at 60 seconds!
That's a really long time! First couple of times I thought the computer had froze. After 60 seconds it will continue booting normally.
Is there any reason why enabling raid causes this to take so long to boot? I've had previous raid 0 setups and nothing took this long to boot.
Also, my HDD on this completely new computer is two Western Digital Caviar WD2500SD 250gb RE drives on SATA cables 1 and 2. The raid array is also
setup up correctly, striped for raid 0.
This is really frustrating because i really like this motherboard. Unfortunately I'm not sure what to do!

SOLVED
Sigh, computers really throw you for a loop sometimes!
I had my Plextor DVD-RW set as master on IDE 1, NO slave (no second drive)
I also had my Benq DVD-ROM set as master on IDE 2, NO slave (no second drive)
Both were on separate cables.
After disconnecting both i the computer booted normally even with RAID enabled.
I found out that setting two masters on two cables on the IDE controller would cause the computer to hang for at least 60 seconds.
SOLUTION:
Use The Plextor as Master, and the Benq as the Slave on ONE IDE cable.
POSSIBLE SOLUTION 2:
Set the Plextor and Benq as Cable Select if using separate cables.
Boots very quickly now. Hope this helps.

10.3 Server new install won't boot from Mirrored RAID - HELP!!

Hi all,
I had 10.3 Server running fine on a 450 MHz B&W G3 (home server use, nothing too demanding), when I decided to add a 2nd HD and run the server from a RAID mirror (both 80GB drives). I had problems enabling RAID on the boot drive with diskutil in Terminal, so I decided to rebuild the server. I didn't have much besides the system on it, so backing up data and re-installing isn't a big ordeal (or so I thought).
No problems creating the mirror set once I re-formatted the drives. The install seemed to go fine (10.3.4 on install disk), but upon restart, I got the flashing system folder/question mark. When booting from the install disk, Disk Utility recognizes the RAID, and Startup Disk recognizes the mirror as a viable boot drive and allows me to select it and restart. Same problem, no system found.
When I run diskutil info for the mirror, it lists the mirror volume as Not Bootable.
I've checked the disks with both Disk Utility and DiskWarrior - all looks OK. I've reset PRAM and NVRAM, taken out added PCI cards, and disconnected all FW and USB devices (besides kbd and mouse).
Unfortunately, B&W G3 can't boot from an external FW drive, so I'm stuck with booting from a CD/DVD for troubleshooting.
My next step is to re-install on a single drive again and try to enable RAID and mirror, but I'd sure like to avoid that if I could.
I've searched through this board and didn't really see this particular situation. Any of you smart server folks seen this before -- any ideas or suggestions??
TIA,
Brad
B&W G3 Mac OS X (10.3.4) 450 MHz, 10.3 Server, 80GB RAID mirror

if you backup your data from a NON-RAID Drive (Single drive), create a RAID array and then Restore from the backup you created... you will find you cannot boot from the drive.
Apparently the sector or drive header information in a non-RAID drive is different than in a RAID array... so when you restore the backup data from the non-RAID drive to the new RAID Array; you effectively corrupt the RAID array not allowing it to be booted from.
The solution is to create the RAID array and then re-install your system from scratch... copying over the data you want to keep from your initial backup one file at a time (don't do a complete system copy or you will once again, corrupt your new RAID install).
I had the same problem and it took me a great deal of time to figure it out.

Rocket Raid 2522 - no localhost/7402 so can't login - help pls?

I havea RR2522 linked to a ProAvio raid drive. It was working fine except my password wasn't letting me into my GUI interface. So I reset it according to Highpoint instructions.
Now I can't login to either https or https://localhost:7402/ and my Raid Drive has dissappeared.
I have tried lots of things including RR4322 Driver that someone on an Apple thread suggested.
Highpoint Customer Service is no existent - and my supplier says - speak to HIghpoint. Last Thursday they took a support request. No answer yet!
I know it works because it did work. Can anyone help pls I am really stuck?
Thanks

Thanks for the report!

NVidia RAID using existing drives?

Hi folks --
Just installed WinXP x64 (build 1218). I've been using an Adaptec 1200A RAID controller with 2 200GB Maxtor PATA133 drives in a RAID1 config.
Unfortunately, there seems to be no 64-bit driver available for that controller card (I've checked Adaptec, planetAMD64, various other places). So the question is: can I set up these drives as RAID1 on the nVidia built-in controller without losing data? These are not bootable drives -- storage only.
The MSI mobo booklet explains a "Rebuild Array" option, where if one of the drives in the array fails, the data on the remaining drive can be mirrored to a new one. Will that work if the source drive was not part of an nVidia array to start with?
I can't afford to lose that data, and I have no place to back it up (without buying another drive). So don't even wanna risk it without some guidance!
One possible complication: the system also includes a Promise Tx ATA133 controller, which is controlling the boot drive (Win64 included a 64-bit driver for this). There is no conflict under Win2k, however.
Anyone have some savvy on this? Or know where to get a 64-bit controller for the Adaptec card?
Thanks!
SYSTEM:
MSI K8N Neo2 Platinum
AMD64 3500+
1 GB Crucial PC3200 DDR
Dual boot: Win2k, WinXPx64
Promise Tx ATA133 IDE controller
ATI 9800 XT
Soundblaster Audigy2
PS: All the rest of this system is working fine, so if anyone is having probs with a similar setup, I'd be happy to help.

Earlier posts on this site, may be in the sata/raid sticky , that the only time a raid can be remade is when using the same controller. Doubt very much that Adaptec & Nvidia raid components are interchangable
i know to my cost on previous rigs that even changing a raid driver has caused the loss of data.
creating a new raid destroys any data on the target drives.
rebuild only applies to drives in an existing array created i would guess with the same controller.
Chances also are that any 64 adaptec drivers will only be beta and your raid may be at risk changing to these from existing drivers.
my advise has to be if u cant back it up dont do it

Nvidia RAID in WinXP64

Hello All:
I have an MSI K8N SLI Platinum (7100 Rev 1.0) board.
It is running the 3.10 BIOS, using a 3800+ X2 'Manchester' rev E4 CPU and 2x1 GB of Geil 3-4-4-8 RAM.
Radeon 300 GPU (yeah, I was pinching pennies when I bought that one).
Seasonic 500 W PSU.
No OC - everything plane jane.
Cool 'n Quiet enabled
Presently I am running XP Pro SP2 and have the following drives:
2 x WDC WD740GD Raptor 74 ('SATA I') - non-raid on SATA 1&2, boots off SATA 1.
2 x WDC2500KS ('SATA II') on SATA 3&4 set up as a Nvidia Raid 0
2 x Seagate Cheetah .8 series 250 GB ('SATA II') on SATA 5&6 set up as SiI Raid 0
This rig runs fine, with very nice benchmarks for the Raid units (well north of 100 MB/s) and good reliability (no RAID disasters [yet]). I mostly use it for Photoshop.
I have tried running Photoshop under WinXP64 on another box (MSI 7207) with 2 x 1 GB RAM ans a 'Venice' 3500+ CPU and have seen nice increases in speed in many functions. However, this system does not have the Raid setup that the K8N SLI Pt has.
So I have been trying to get XP64 to install on the 7100 (K8N SLI Pt) machine.
I do the dance of two floppies with the NVidia RAID and SiI Raid drivers during install and set XP64 up on the second Raptor on SATA 2. (XP Pro is on the onther one on SATA 1).
When XP64 boots the machine hangs. I can boot into 'Safe Mode' but running MSCONFIG and disabling all the driver loading does not help - it still crashes when I boot XP64 in anything besides 'Safe Mode.'
I have tried an install w/o any of the RAID drivers and got a stable SP64 boot.
I ran MS Update and got all the relevant XP64 updates (my install disk is SP1, which is the latest SP for XP64).
I then installed the SiI drivers using Device Manager - that worked OK. Nice box, Photoshop CS2 ran well, the SiI RAID gave nice benchmarks, etc.
I then installed the Nvidia RAID drivers using Device Manager - dead box with the same issues as above.
I have also tried an install with the SiI RAID drivers only and also got a stable SP64 boot and a dead box when I installed the Nvidia RAID drivers using Device Manager.
All drivers are all the most recent release (no Betas) downloaded off the MSI site, with the Nvidia RAID set dated 8/1/2005.
Right now I'm blaming the Nvidia RAID drivers, but am open to suggestion.
Anybody had experience with XP64 on this setup?
Thanks,
ss

To clarify:
The rig in question (in the post above) is:
MSI K8N SLI Platinum (7100 Rev 1.0) board.
3.10 BIOS
CPU AMD Athlon64 X2 3800+ 'Manchester' rev E4 CPU
2x1 GB of Geil 3-4-4-8 RAM dual channel DDR 400
Radeon 300 GPU
Seasonic 500 W PSU.

Stable operation under XP Pro SP2 with the drives set up as follows:
2 x WDC WD740GD Raptor 74 ('SATA I') - non-raid on SATA 1&2, boots off SATA 1.
2 x WDC2500KS ('SATA II') on SATA 3&4 set up as an Nvidia RAID 0
2 x Seagate Cheetah .8 series 250 GB ('SATA II') on SATA 5&6 set up as SiI RAID 0
This mobo uses an Nforce 4 SLI chipset. I believe the Neo 2 Pt uses an Nforce 3 chipset.
Yes, I am using the latest MSI-sourced drivers with the XP64 installs.
The question is: has anyone gotten Nforce 4 SLI chipset Nvidia RAID to work with XP64?

Problems w/ on-board NVidia RAID + PCI RAID on P7N Diamond

Here's the setup and issue.
I'm booting off of the on-board NVidia RAID on my P7N Diamond. It's RAID5 w/ 4 WD 640GB drives. Works fine.
I've recently pulled a NetCell SyncRAID SR5000 PCI RAID card (runs an adapted RAID3) from an old system where it worked fine and was NOT the boot drive...just storage. Plugged it in the one and only PCI slot on my P7N Diamond. Once it's in, the system will no longer boot.
When the PCI RAID card is not installed, the mobo's BIOS boot menu shows "NVIDIA RAID5 1". As soon as I install the PCI RAID card, the NVidia RAID disappears (no longer an option at all) and is replaced by "IDE:Revolution". At that point the system cannot find any bootable source and fails.
I also get an error message "Not Enough Space to Copy PCI Option ROM".
Unfortunately, MSI's tech support is passing the buck on this one. They're saying:
Then sound like the card and the board sata controller are not compatible. If the card is connected it disable the onboard SATA controller. Once the card install the port is enable again. please check with the card manufacture. thanks
I really find this annoying as the card works just fine in other systems. It's having an issue WITH THIS MOTHERBOARD, but they tell me to go to the card manufacturer. The real problem is NetCell went out of business a few years ago, so they're not available to go to.
So, the quick and dirty is the manufacture of the only motherboard I've had a problem with concerning this card won't help, and the card manufacture cannot be reached. I'm hoping someone here may come up with a workaround.
I'm trying to consolidate down to 1 computer, and I specifically purchased a case and power supply with this RAID migration in mind. I'm gunna be PISSED if I can't use a RAID array I spent close to a grand for (a couple years ago)!

MSI continues to blame the chipset or PCI card for the incompatibility (not the motherboard), saying there's nothing they can do.
Does ANYONE have an idea other than setting aside my RAID array?

Mac Pro shuts down after setting up RAID (HELP!)

So, I recently purchased a rev 1 Mac Pro and decided to setup a RAID using 4 750gb WD drives. I am not using a RAID card, simply using Disk Utility.
I first combined drives in bays 1 and 2 (striped) and then combined drives in bays 3 and 4 (striped) to give me essentially two 1.5tb drives.
I then created a mirrored RAID using the two striped raids so that I would have the speed of a striped RAID with the safety of a mirrored RAID.
Once I did this, it showed up as one hard disk on my desktop (I was booting with an external). I then cloned my external drive to the new RAID disk on the desktop, and did so successfully.
However, now when I try to boot from the RAID, it chimes, the Apple appears, and then the Mac Pro shuts down. I tried holding down option and all 4 drives appear. I tried booting from a different drive, and the same thing happens. I should also note that the firmware bar flashes on the screen before shutting down (looks like a really long pill).
Any ideas? Does it sound like I did something wrong? I hate to start from scratch, as it takes all night to clone my external drive to the Mac Pro. Thanks for any help.

Hello, Hatter. Thanks so much for the information. I went with the information from the Macworld article (I believe) "RAIDing the Mac Pro" and according to it this setup was supposedly a great idea. But, yes, it's not working out so perhaps not in this case.
So, I have four brand new 750gb Caviar Black drives installed. If I understand you correctly, I should stripe 3 disks together, then use a 4th as backup (using Time Machine?). So, if I use the drives I have, I'll have a striped configuration that gives me 2.25TB of space, and a 750gb hard drive for backup. That technically would work for now, as I have about 660gb of data on the system (although in the future I'd need to swap out that 4th drive for a 2TB.
So, if that is what you're suggesting, would you mind telling me exactly how I do that? I think I understand, but just want to make sure as this is my first Mac Pro and first time setting up a RAID. Thank you so much for your response.
p.s.: I'm guessing I'll need to do a fresh start and clone my external drive all over again, correct?

Moving boot disk to raid 0

Hi Guys,
I have the following volumes on my MacPro
1. Boot Disk - 465.3 GB, 200GB used
2. Raid 0 volume - 436.2 GB
How easy is it for me to move the boot disk data to the raid 0 volume and then boot from the raid 0 partition.
Also I have heard that if you have a raid 0 boot disk that the firmware updates can fail, is this still true.
Thanks for any help
Andy

Quicken Data files are actually packages, which can contain alias to the volume. Once I stripped the aliases from the data file, no problems, but for the longest time (years) everytime I cloned and used a different volume I'd run into trouble.
LittleSnitch hard codes the volume name, but also WHERE on the volume, an application is located. Very annoying.
So it may be plist or preference, but it could also be writing an alias to data file, or even back to the application package itself.
You would think at some point during testing especially, a light bulb would go off and realize there is a better way to code (unless it really is deliberate and trying to tie a program to only a single volume type system, which the Mac doesn't need to be).
Feedback the vendor. However, unless you do a lot of moving stuff around (like during testing) it is a "once only" event. If you name the new RAID boot volume with same name, might not even matter.
I do a lot of backup and restores during the course of a week, SuperDuper works well, not 200% perfect maybe, but works.
I keep my boot volume, though, free of my home account. That resides on another volume and can last for years. The boot volume gets changed more often. And I think having "home account" (but not /Users) not be on the boot drive makes it easy and avoids some of these problems even.

K8n platinum NVIDIA RAID IDE ROM BIOS Hang *SOLVED*

amd 64 3500+
msi k8n plat SLI
NV 7800 gtx
2gb corsair xms3200 (2x512 1x 1024)
500W PSU
40GB IDE maxtor (windows install)
System hangs on the NVidia raid ide bios screen, doesnt matter if i disable raid or not, system just wont get past this screen. There is a flickering cursor as if the system is trying, but its got no further after 30 mins.
ideas please? any more info you need?
thanks,
Dan

Quote from: dandut on 23-July-05, 07:50:41
If i disable raid, i still get the NV IDE BIOS screen, it just shows a message other than 'detecting array' with a flashing cursor and does exacly the same thing. It just wont get to the next stage.
I havent tried flashing the bios yet as my floppy seems to be dead. Could that help? Im not entirely sure if its the raid screen causing the problem anyway, it could be whatever is supposed to happen next, that just isnt.
p.s. Clearing cmos didnt help.
[/quoteTry flipping the cable over on your floppy drive.

Nvidia RAID Driver Disk

Nvidia RAID Driver Disk
The problem is with trying to Install Windows XP [Upgrade]. (Clean Install)
K7N2 Delta2-LSR
I tried using the nForce3 SATA RAID Driver For Win2k/XP after pressing F6,
during XP Install.
They don't work, and after trying a couple of times - got an error reading.
This Motherboard has an nForce2 Chipset, so I read the Manual.
It showed how to make an Floppy SATA RAID Driver Disk.
I tried to copy the SATA RAID Drivers from the MSI Driver's CD - but
got Disk Full.
Then I downloaded an Program to Format Floppy at 1.72MB, and copied
all the necessary files to Floppy.
Tried using it after pressing F6, but got Error - Unrecoginized Format.
(The Floppy did read OK, MS-WIN ME)
BTW I thought this Motherboard used nForce2 SATA RAID, why they include
nForce3 SATA RAID Driver Floppy - I wonder.
Any way to get SATA RAID Driver's that will fit on FDD 1.44MB ?
[size=18]TheCyberDude[/size]

[size=18]UPDATE[/size][/b]
I looked at the nForce3 SATA RAID Driver, and the Folder raidtool was not on it.
They Manual said to copy all files (Including Folders) to Floppy.
(This wasn't posible, because of size limitation - 1.44 MB)
So I made an SATA RAID Driver from the MSI CD, except I didn't copy the
Folder raidtool.
I tried to install Windows XP Again, it Took the SATA RAID Drivers OK -
but after it said Setup loading files and the STALLS at Setup is Starting
Windows.
Tried it again, except this time I got this error:
(File txtsetup.oem caused an unexpected error (1024) at line 1747 in
d:\xpsprtm\base\boot\setup\oemdisk.c.)
If I don't Press F6, it shows the partitions:
39080 MB Disk 0 at Id 0 on bus 0 on atapi [MBR]
C: Partition1 [FAT32] 78160 MB (77280 MB free)
39080 MB Disk 0 at Id 0 on bus 0 on atapi [MBR]
Unpartitioned space 39080MB
I was able to Format with NTFS (Successfully), but it wasn't recongized.
(Figured that it wouldn't - Because I was able to get SATA RAID Driver's loaded Successfully)
Just wanted to see what it would do.

Image Software on nVidia RAID arrays

Has anyone been able to get a disk imaging program to work with the nVidia RAID array? I have tried Acronis True Image, Norton Ghost 9.0 and the old Drive Image. I have been unable get the rescue/recovery disks to recognize the RAID Array. With Acronis, it appears that they don't have the Linux drivers for the RAID array. Ghost 9.0 is supposed to support RAID arrays, but when I try to load the drivers, I get a message that it can't find nvraid.sys, despite the fact that I supply that file on the floppy disk. I spent 1.5 hours on the phone with Symantec Technical Support and their only answer was that I would receive a phone call from a supervisor in 3 days.
I can get Norton Ghost to work from within windows, but in order to restore an image of my C: drive I need to gain access to the RAID array from the recovery disk.

I have sort of got it to work with ghost9 .
I have written a plug-in for nvraid/nvide for the bartWinPE cd made with PEBuilder 3032.
V2I Images can then be browsed with imagebrowser and files/catalogs be restored
to arrays partitions .
The thing that does not yet work properly is the V2I protector executable cause the bart plug-in for .Net gives problems .(not sorted out this yet)
The BartWinPE cd is also of course equipped with ghost9 plugin .
So basicly the PC is booted with bootable Windows PE cd (like the ghost9 CD) ,
windows runs from cd&ram . And all the nvraid arrays is visible .Restoration made
with V2I image browser .
The plug-in ( INF file ) :

If the BartWinPE cd is equipped with ghost8 you should be able to restore
full disks/partitions with the *.gho extension .
But then the images must be buildt with ghost8 (from the BartWinPE cd first).
Though i have not had the time to test that yet .

Hello,
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitirion & use Disk Utility from there.

Booting to Nvidia Raid......HELP pls!
