Right now I am usually booting the stock 2.4 kernel (in 7.1), although I have also booted the 2.2.18 kernel. I installed Lilo in the /boot partition because I use Boot Magic on my machine.
I have three hard drives on the machine plus a CD-ROM. I tried putting my Linux drive (Maxtor 20G 7200 RPM ATA 66) on one of the motherboard IDE controllers, but I had no end of problems. I think it was a problem with the motherboard BIOS (at least according to Maxtor it was), but the motherboard manufacturer has not updated their BIOS since 8/99! So that's when I decided to put it on the Promise Ultra66 card.
I boot Linux off of this controller all the time - I just added Linux to the Boot Magic configuration, and told it which drive to use. So far it hasn't been a problem.

Hi mike, and all,
thanks alot for the verz fast reply, maz i inquire about your kernel version?
I want to use this controller for mirroring and striping, if possible with the hardware support for these operations.
Also, mike, do you install lilo in the MBR of hda? I would like the drives connected to the Promise to be the onlz drives in my system. So i was wondering, if i could easily boot of this controller...
I know, it is possible to do mirroring and striping using linux software, but doing it in hardware would be alot nicer....
Anybody?
And best regards, Alex

I'm using a Promise Ultra 66 PCI card for my Linux drive. It seems to work fine - Linux recognizes the drive no prob. However, I do get some funky lilo messages, but I'm not sure if they are related to the promise card or not. Here's an example:
linux:~ # lilo Warning: /dev/hde3 is not on the first disk Warning: BIOS drive 0x82 may not be accessible Warning: BIOS drive 0x82 may not be accessible Warning: BIOS drive 0x82 may not be accessible Warning: BIOS drive 0x82 may not be accessible Warning: BIOS drive 0x82 may not be accessible Added linux * Warning: BIOS drive 0x82 may not be accessible Warning: BIOS drive 0x82 may not be accessible Added linux_2.4 Warning: BIOS drive 0x82 may not be accessible Warning: BIOS drive 0x82 may not be accessible Added suse Added windows Warning: BIOS drive 0x82 may not be accessible Added memtest86
Anyway, it all seems to work....:)

hello all,
could somebody post experiences with ultra66 controllers available as pci cards.
I was opting for a promise fasttrack 66, but i read in the udma howto on linuxhq.com, that it was problematic to install with *recent* 2.2 kernels. As this document may be outdated, could somebody tell me (or point me to info) if this problematic situation is still the case?
any other recommendations or tips?
best regards, Alex

Are you asking if Linux can be booted from a drive attached to ide2 or ide3? Or is mirroring the problem? I don't know about the second question, the first one can be answered with yes, though. Just make sure your kernel supports the Promise Ultra 66---depending on what kernel you use this may require Andre Hedrick's IDE patches (you need them for non-SuSE versions of 2.2.x but not for SuSE kernels or for 2.4.x). Then you'll have to switch some BIOS setting (in my Award BIOS it's `HDD Sequence SCSI/IDE First: SCSI'). That's it.

Hi Stefan (thanks for your quick reply) and all, <my original post is below> Concerning the bootablity of the promise controller... that is excelent news, but the main problem may be the mirroring (that the promise controller should be able to do in hardware). I want to do the mirroring for reasons of redundancy. I know, that todays ide drives are less prone to hardware failure than older drives, but the box is supposed to be a locked-away-closet-box, that will be a few hundred kilometers away from me, so the system should be a able to automatically detect drive failure, so that the running system can switch all request over to the working mirror-drive transparently. I would also like to know, how i could automatically detect such a failure, so that a script can send me an email, to inform me about the failure... hint, tips, suggestions, pointers anyone? thanks already in advance best regards, Alex

You can't use the RAID support of the Promise controllers, at least not yet. For the most part because it's really only software RAID done in the BIOS. If you want real hardware IDE RAID your only choice is one of the 3ware controllers, which come with 2, 4 or 8 ports (one drive per port). These controllers have their own processor to offer hardware RAID (levels 0,1,5 and 10) and are well supported under Linux. Check out http://www.3ware.com for further info. Currently the Promise controller is only supported as a normal ATA100 controller (and expensive at that) under Linux. Philipp Thomas -- caffeine low .... brain halted
