Hi First of all, PDC card does not give you true raid. It gives a little better than software raid (software raid + bios hack). So, evenif you ignore ataraid and use simple software raid in Linux, no big deal. pdcraid module now supports raid-1 (mirroring) I am using mirroring in RH7.2. You can check my homepage to see how I did: http://solar.murty.net/~murty If you want to disable raid support in motherboard, you dont have to. If you dont want to use Promise RAID, then just dont load the raid module in linux. (PDC202xx module loads anyway first) Good Luck Murty On 10 Apr 2002, Jinn Koriech wrote: > hi all - i'm new to raid and i've a couple of questions regarding the > promise fasttrack (lite:( {so-called} raid support. i've got an msi > mobo with the pdc20265R onboard and promise fasttrack bios 1.3.? > > from what i understand the ataraid module with the pdcraid module > together only support raid-0. now, i had a tough time finding any > information on the web about how the promise pdc20265R was supported > under linux and i'm now kicking myself to get some raid-1 working here. > anyhoo - i eventually found this gpl ataraid project and am very > greatful for all the support and effort you stars are putting into this. > as my contribution - if i can get this working - i'm going to write the > how-to for other late-night devotees. > > ...but i've pretty much given up on the (no)promise raid for now. or am > i getting disheartened too soon? > > following my pains my plan was then to simply set up software raid over > the main ide bus, but then i don't have anywhere for the dvd+rw (it > won't work as a slave on ide1). > > so now i'm stuck here -> i can find no indication whether it is safe to > turn the onboard raid support back on and set up software raid over the > extra ide ports made available, and if so how i should go about it. is > the ataraid needed with software raid running on ide3 & ide4? do i > proceed as outlined in the software-raid howto / boot+raid+lilo howto? > or is there some critical no no i'm about to commit here. > > i pray that one of you guru's has the answer cuz i can not think of > where else i may go next. > > thanks in advance for even reading this. > > jinn > > ps - just incase late night delerium is making me gugel-eyed and absent > minded: i'm trying to get this all up and running on mandrake 8.2 with > two ata100 drives and a dvd+rw. other than that it's a pretty standard > system (except for the [no]promise). fyi mandrake 8.2 comes with kernel > 2.4.18. > > also - i've installed the raidtools-0.90 and /proc/mdstat still only > reports the following: > > Personalities : > read_ahead not set > unused devices : <none> > > > > > _______________________________________________ > > Ataraid-list@xxxxxxxxxx > https://listman.redhat.com/mailman/listinfo/ataraid-list >
