Booting from eSATA2 RAID Cards??

is this possible yet?
if so, which card(s) support it?
Quad G5 Mac OS X (10.4.4)
thanks

Hi,
Since you have a PowerMac G5 Quad (Oct 2005 model),
the answer is NO. The new Sonnet Tempo E4P is an awesome SATA card for a Quad but it does not support booting. It does support direct connections, port multiplier enclosures, hot swap, sleep mode, and has four external eATA ports. But NO Boot capability.
I have talked to several SATA host adapters and from what I have heard none of them expect to add boot capability to SATA host adapters used in a PCI Express (PCIe) slot. I want boot capability too but it does not appear that will happen with a 4 port external PCIe card. The FirmTek cards can boot with PCI-X but PCIe is not as easy to implement booting on.
There is also a train of thought that companies do not want to put a lot of development time into the Powerac G5 PCIe models as some developers believe that the PowerMac Pro (Intel model) will be released in the next 4-6 months with a totally new expansion bus and it will require all new intel software to operate. As this is the case, the PowerMac G5 PCIe market may be limited and developers need to make their dollars back on a stable product cycle.
There are also hints that the new PowerMac Pro (Intel model) may have dual external SATA ports which would allow SATA users to use up to two drives externally without a SATA host adapter. Those that want more ports will purchase a host adapter as well.
The future is bright but the PowerMac G5 Quad appears to be a limited development opportunity for some companies.
In other words - do not expect a bootable SATA host adapter solution for the Quad.
Wishing I was wrong,
Michael

Can a6614f boot from PCIe x1 card?

I've got an a6614f desktop PC. There are 4 SATA connections on the motherboard and they are all used up (2 optical drives, 2 HDDs). I've got an SSD coming and will be getting a PCIe x1 card to add more SATA ports. (PCIe x16 slot is being used by my GPU.)
Once I have the PCIe card installed, I'll have the option to plug the SSD into the card or directly to the motherboard. I've been told that the speed on the PCIe card will probably be faster than on the motherboard, so if possible I'd like to connect the SSD to the PCIe card. My question is, would the system be able to boot from a PCIe card?

Hi,
I would buy one of these PCIe cards:

Now you may connect the SSD directly to a SATA slot on the motherboard and one of the HDDs (I'm guessing that the SSD will be a boot drive) or optical drives into a slot on the PCIe card.

T440s Boot from SD(XC) Card

Hello,
is the T440s capable of booting from an SD card? I installed Ubuntu 13.10 + GRUB bootloader on a SD card but the card doesn't show up in the boot device list. Has anyone an idea what the problem could be?
thx
Schaber

Sure it can. You just need a little bios hack. Google and you'll find all sorts.

Will mavericks boot from a raid array?

Will OS X Mavericks boot from a raid array? I know Lion didn't support booting from a RAID.

Well, since no one seems to want to answer this question I've done a little research and answered it myself. Yes, you can boot from a RAID while running OS X Mavericks. The only setback is that you can't create a recovery partition.
While installing Mavericks on a RAID it will prompt you to OK installing without a recovery partition. In laymen's terms it means you have to keep your own backup. If your RAID fails you will lose the data or whatever is stored on it. Simply keep your own backup and you'll be fine. This is the way most people do it anyway. Yes, it may be considered old wave but it's still the best option. It's an absolute. If you have a backup, you never to have cross your fingers, pray and hope the recovery process actually works!
That being said, you can create some really souped up Macs. I actually installed two 480GB SSDs into a 2.8GHz Macbook Pro and the response is phenominal !!! From power on button to sign in screen is less than 10 seconds on a 5 year old Macbook Pro !!! If you hate seeing the little spinning wheel while shutting down this will cure your distress. Shutting down is instantaneous. I love it !!! RAID and SSDs are the best !!! A newer Quad-Core machine has to be even faster which is hard to imagine.
That's my 2 cents ...

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

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.

TS 100 No boot when Rocket Raid Card configured

I have a Rocketraid 2320 controller. With the card installed and NO raid configured I can boot to the MS server 2003 Standard cd disk. With the raid card configured I cannot boot to the CD drive. I also installed a SATA drive (not on the raid) installed MS server 2003 standard, all is well until I configure a raid array on the Rocketraid card.
I then only get a flashing cursor and no boot. I have changed the boot order to Boot Hard 1st then Rocketraid then CD rom and all variations of those devices. What am I missing? Thanks. Dave

Thanks Gabor, for the response.
I refered couple of answer records like AR# 34873 and AR# 34894, I monitored trn_reset_n, sys_reset_n, clock_locked, PLLLKDET and RESETDONE signals as suggested in AR# 34894.
Status as follows:
SYS_RESET_N = 1 (deasserted)
TRN_RESET_N = 0 (asserted)
CLOCK_LOCKED = 0 (deasserted)
PLLLKDET = 0 (deasserted)
RESETDONE = 0 (deasserted)
which means the transceiver PLL frequency is not within the predetermined tolerance. Is this problem related to the PCIe Jitter Attenuator I am using on the board to derive 125MHz from 100MHz system Clock.
Thanks & Regards

Can't boot from IDE RAID 0 on K7D

I'm running the K7D with the latest BIOS, with two MP 2000+ processors. In PCI32 slot 1 is my adaptec 1200A IDE RAID controller, with one WD Caviar 1200JB set as the master drive on each of the card's IDE channels.
With the drives set for RAID 1 (mirroring), I have no problems. I can install Windows 2000 Professional, and I used it for weeks with no significant problems.
With the drives set for RAID 0 (striping), Windows 2000 installs just fine, but the K7D will not boot from the array. If I boot from a floppy or a CDROM, The Win2K boot loader has no problems loading win2k from the RAID 0 set. But the K7D does not find an MBR on the array.
Where could the problem lie? My Award BIOS boot order is CDROM, SCSI, HDD0. The array is marked as bootable in the RAID card setup.
Thanks --
Neil

no Paazel...
this is the right forum for him
his board uses the AMD chipset... this is the AMD chipset forum...
i think he has a MSI K7D Master-L 760 MPX
witch is a dual prossesor mobo. with the AMD chipset.

Can not boot from a RAID 5 volume

Dear Friends,
I have a Mac Pro (3 GHZ) with RAID that will not boot off of a RAID 5 volume. Here's the details:
The unit has 4 768 GB drives that I have made into one RAID 5 set. After that I broke it down into 2 two volumes one for OS (200 GB) and one for storage (the balance of the RAID). After that I copied a known good image to the OS volume.
The Start-up disk utility on the DVD sees the OS but when I boot it sits for a long time and eventually gives me what Apple calls the prohibited icon; a circle with a line-through it like Ghostbusters.
The patron table is good, and I have done this on another Mac Pro. I have tried to rebuild the RAID a few times with no luck. Ideas would be appreciated. Thanks!

My guess is that the Mac OS X system is damaged. You may need to use the Sysytem CD to perform an archive and install.
For those interested in bootable RAID cards on the Mac Pro, the Areca is the only non-Apple solution that I have found with this capability. You can read more about it here:

Have fun!

Can I install Snow Leopard and boot from software RAID 1 (mirror)?

I have a Mac Pro (quad core 2.66 GHz) on order for my office workstation. Yeah, I know new ones are probably coming out early next year but due to budget and upcoming projects I need one now. What I'd like to do is replace the pre-installed 640GB drive with two 1 TB drives and mirror them. The 640GB drive will be redeployed to another machine in the office. Can I boot from the Snow Leopard install DVD, go to Disk Utility, setup a RAID 1 with the two drives, install Snow Leopard to the mirror and then boot off the mirror set?
I've searched and found offhand comments to the effect that installing to and booting from a software mirror is OK, but I'd like to know for sure that it's OK. Any experience that you have with such a configuration would be nice to hear.

Yes. But before you do read the following:

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?

MSI845PE Max2: booting from the RAID controller

Hi,
I have an MSI 845PE Max2 motherboard. This board comes with 2 extra IDE connectors from an onboard RAID controller. I managed to put this controller to work as a regular UDMA133 controller with an modified BIOS.
I have a CD-ROM connected to one of those IDE connectors. The CD-ROM is detected, but I didn't manage to boot from that drive.
I tried to alter the boot sequence on the BIOS. I even disabled the 3 pre-configured steps, leaving the option "Try other devices" enabled, but still wasn't able to boot from the CD-ROM.
So, this is my question: it there any way to get a drive (wether it is a CD-ROM or a hard drive) to boot, when it is connected to the RAID/UDMA133 controller?
Best regards,
Norberto Henriques

I Download mod bios and went to flash and the Msi instructions on flashing were insufficent for the job. For one thing when I got to A prompt after bios. There was no c drive detected. Couldn't get to bios in C:test. Hard drive was connected to Ide 3 where i installed it with the 133 drivers during installation. I tried connecting it to Ide 1 to see if it would boot. It did and seemed to work but still couldn't get to c drive from A prompt after bios with C: . Tried booting with Me Boot Disk (the one I installed Me with on other systems). There was no ramdisk loaded. It just acted like I wanted to install Me. I gave up on the flash (but still would like to know how??) Got my maching running with 430watt antec, msi 845pe max2-fir, 40 and 60 gig maxtor 133 drives, pent 4 2.4B ghz. asus Dvdrom and Asus cdrw,512Mb crucial 2700,Radeon 8500LE,Sound Blaster 5.1. Had only a few problems. Still trying to figure out some of the Bios settings. Will post more later if anyone can help. P.S. How do you get all your statistics to show up at the end of your post without typing it out each time?? Any help appreciated. May the force be with you

Wind PC - How to boot from internal CF card?

I installed a 4GB Lexar 300X UDMA CF card in the internal slot and did a fresh install of Windows XP SP2, but after the install I get a disk error after the Bios posts. How do I make the CF card bootable. I tried formatting with NTFS and FAT32 and it's no help.
I don't want to use a regular HDD to boot from.

Is this with a CF/HDD adapter as a replacement for the original HDD or are you trying to do this through a card reader?
Edit: Unless I'm misstaken you can only boot an OS using the CF & adapter as a solid state HDD replacement. If I'm wrong anybody that feels like it can say so.

How do you boot from IDE3 RAID

I have just installed a new HD on IDE3, no issues getting the bios to recognize it. However if there is a bootable HD in IDE1 it will boot from there and not from IDE3, regardless of what I do. I have tried in the BIOS disabling all boot devices and to boot from HDD-0/3, but it always boots from IDE1.
I think this is a BIOS glitch as there sould be a boot from RAID controller option.

This is an upgrade of an aging GigaByte system. I had Windows 2000 installed on the 20GB drive, and VERY heavily customized. What I wanted to do was set up the WD drive as a RAID array (with eventual plans to buy another drive and mirror it), and then use PartitionMagic to copy/move the original partition from the 20GB drive to the new WD drive, and then remove or reformat the old drives as "archive" drives. I desperately need to carry over the original Windows 2000 and installed software, or I face literally months of trying to reinvent all the customizations (and some maybe never: I've forgotten how to get rid of the stupid "assistant" in Outlook 98).
The problem: Windows 2000 is now seeing the WD drive as physical disk 3, which will f**k up the boot loader in the copied partition, which expects to be on the first partition of the first physical disk.
In the meantime, I've been forced to do a new Win2K install to the WD drive (seen as E:), with the original install on the 20GB drive (still seen as C:) so that I can reach the 'Net and things like this forum. :-/
The original install shows up in the boot loader now as an option, but of course isn't bootable with the MSI board yet because all the old GigaByte drivers etc. are still being used. I can fix that eventually, but then there's this problem with the physical ordering of the disks.
I can't simply move the WD drive to IDE1 and move the original bootable disk elsewhere, because then the original won't be bootable (different physical disk), and I wouldn't be able to later create a mirrored array with the WD drive.
I need to have the motherboard/BIOS report the RAID array as physical drive "zero"; is there a way I can make that happen, or is there another way to do what I want that I'm not seeing?

Mac Pro Boot from PCIe SATA Card

Is it possible to boot a Mac Pro from a PCIe Sata adapter? I bought a PCIe SATA III card to connect to my 64 Gb C300 SSD Drive. The internal SATA II drives are not fast enough to take full advantage of the C300.

Old Thread But Great News for MAc and PC Laptop Owners I know and trust this company and just bought this for my MAc Pro it boots up the hard drive a couple ways. In Mac hold down the option key and or once in MAc OS tell it to startup disk the external Sata (eSATA)
Worked 100% on my Mac Pro 2008 and this works on Laptops Mac and Windows
One catch its expensive but can go up to 6G WOOOOOOOOWs
Only card out of TON I have tried that will boot at least MAc OSX dunno about windows/Boot Camp but I think theoretically it will with the "Option" key wait and be patient and once you choose the sata drive maybe you can boot boot camp dunno? Actually yes you can once you set the startup disk to the esata boot camp windows will boot!!! Wooooooooot

Boot from Software RAID

I need help setting this up. My main aim is to get a RAID5'd /home directory, however having the rest of the stuff on the Raid would be convenient. I've followed arch wiki guide but I just get this error when trying to boot:
IP-Config: No devices to configure
Waiting 0 s before mounting root device...
ReiserFS: md0: warning: sh-2006: read_super_block: bread failed (dev md0, block 2, size 4096)
ReiserFS: md0: warning: sh-2006: read_super_block: bread failed (dev md0, block 2, size 4096)
kinit: Unable to mount root fs on device md0(9,0)
kinit: init not found!
Kernel panic - not syncing: Attempted to kill init!
I've followed the guide on the wiki several times. I've also defected to the gentoo wiki but no hope.
I've tried to reboot with the CD and mount md0 (and 1, 2, 3) but it won't, it tells me to specify a file system. I can't access my grub loader but it looks precisely like the one on the wiki.
Could the problem be that I'm using sata discs? I'm pretty tired of trying things now, I'll go to bed and hope some kind soul will extract me from my non-parity hell.

Is it strange that after the Kernel panic, if I reboot into a live cd and try to mount /dev/mdx it doesn't work? And that I can't mkreiserfs on it?
The machine actually started after my install this time, but it's just gone back to it's recidivist ways now. As far as I can tell, after a reboot the RAID is no created properly. I setup mdadm.conf, mkinitcpio and grub all as the wiki.
Can someone post exemplars for what I need to have in these files? My arrays are arranged thusly:
md0 is root, raid = 5, discs = /dev/sda3 to /dev/sdd3
md1 is swap, raid = 0, discs = /dev/sda2 to /dev/sdd2
md2 is boot, raid = 1, discs = /dev/sda1 to /dev/sdd1
md3 is home (LVM), raid = 1, discs = /dev/sda4 to /dev/sdd4
It is possible to install on another hardrive and just mount the raid as a directory but I'd need another disc for that
Also, this should possibly go in the Newbie section because it's probably really simple :embarrased:
