I'm brand new to Linux and just purchased The Complete Linux OS 6.5 (Linux-Mandrake 6.1)  I printed out everything under Device Manager in Win98.  Under SCSI controllers, I have Device:  Promise Technology Inc. Ultra66 IDE Controller.  However, when I go to choose this when I'm asked if I have SCSI controllers in the installation there isn't a choice for it.  I tried selecting anything, but none of the other devices are to be found.  I tried selecting 'No' when asked about SCSI controllers just to see what would happen and I get an error message of, "...no valid devices were found on which to create new filesytems...".  Can someone please help me?  Thanks.

This isn't a scsi controller Utra66 is an IDE technology and will therefore install by default.  However, you can't use UDMA 66 support under linux yet, so the device will use UDMA 33.

It isn't installed by default...  If I choose no, I get the error message I mentioned previously.

Go into your system bios and make sure that you internal ide channels are not blocking the ultra ide card.  you may want to try to disable them.  you will probably have to eliminate any LBA mode type settings for your controller and hard code the disk drive geometry settings that are printed on your drive itself.  Hope this helps.  I have seen other posts here for Untra DMA66 type cards...try the knowledge base on this site and see if that doen's have the answer you are looking for.

Ok, I have the same card, you have to boot like you are installing the OS, and go though the screens until you reach a screen that says Install or upgrade. Then press Alt+F2 (i think, it is the one to get you to a bash command) Type cat /proc/pci then notice the text at the bottom of the screen, it will say something about the Promise Ultra.... and will have about 6 rows of information. The first to numbers is what you need, (e.g. Mine was 0x10c0 then 0x10b4) they will be like

       xxxxxx 0x10c0
       xxxxxx 0x10b4
       xxxxxx xxxxxx .... and so on

take these numbers and write them down. Next time you boot, it comes to the boot# type in "linux ide1=0x10c0,0x20b6" the numbers might be difrent, (by the way, the second number is the number plus two, it was not a mistake, so if you had 0x10f3 it would be 0x10f5) it will pause for a second befor it loads to install, then you should be able to edit the partitions.
