Hi While it may or may not be possible to disable raid feature on Promise card by pulling a jumper, here is a better solution: Disabling Promise RAID (just use it as IDE controller without FastTrak): In the FastTrak BIOS, choose SPAN with only the first hard disk. Say NO or OFF to all silly options such Gigabyte boundary etc. You can do the same thing with Striping (i.e Stripe but with only one disk with all the options OFF) but I prefer SPAN. This way, you can boot your Promise Array (which happens to be just SPAN with one disk in the above case), pass Append Line for booting Linux (not required for RedHat 8.0) and use the disks as simple IDE disks. TIPS: 1. Delete disk array in FastTrak BIOS (i.e. no raid defined therefore disks not bootable), boot off of RedHat CD #1 to install Linux. Do all your disk partitioning. Then reboot. 2. ONLY when you are done partitioning the disks and you rebooted and made sure the partitions are all there, you should create any raid in the FastTrak BIOS. 3. At the time of compiling kernel: Unselect "Special FastTrak Feature" (because we DONT want to use FastTrak BIOS) Select Promise Controller support PDC20xxx (not as module). If you dont select this your kernel probably will not boot or will boot but DMA is off Unselect Promise Software raid (because we want a non-fasttrak ide box) 4. Run hdparm utility to make sure your both disks have dma enabled and time cache reads and disk reads hdparm -d /dev/hde (check if dma enabled) hdparm -tT /dev/hde (time the reads) (Please be awake when using hdparm command so you dont pass any wrong options by mistake!) 5. You may have to pass at the time of booting idebus=66 Comments welcome On Fri, 24 Jan 2003, Michael George wrote: > On Fri, Jan 24, 2003 at 03:12:49PM -0500, Michael George wrote: > > I have heard that removing a jumper from the FastTrack 100 TX2 will allow it > > to act as a regular ATA controller.
