Re: Help on FastTrack Ultra66 card

From: Chris Chabot (

Ive tried this ide patch from hedrick, but it doesnt seem to fix the situation. (the specified patch +
clean 2.2.14 kernel). Its still only finding 2 drives, each of 20 gigs .. the actual reported size is
different though, but the ide probe resets it back to 20 gigs. (see below). When i try to specify a
    hde=39703,16,63 (bios reported geometry)
    hde=9964,255,63 (fasttrack reported geometry in bios menu's)

it does get the right size (aprox 78 gigs), but when i try to write to it, i get a ide seek error at 20
gigs (eg the physical end of a drive), and it isnt able to use 78 gigs ...

Ive also tried the ide2=four and ide2=0x4b00,0xa800,11 options, with and/or without the above, but it
didnt want to cooperate :) (got the above options from Documentation/ide.txt, for cards that have 4
drives on one port, 'stead of the standard 2)

Also before you ask, i did enable 'generic 4 drives per port' and 'enable dma' together with the
pdc20262 (aka promise fasttrack ultra66) driver, and the promise fasttrack is configured for one big
raid 0 array

Ive included some information from /proc & startup below, hoping that it might help ppl see whats going
on ... im dying to try out this raid controller! :)

ps note the /proc/ide/hde/geometry results, the difference in reported vs actual size, reported is 78
gigs, actual is 20 gigs ..

pps i also have a normal 20 gig maxtor +cdrom on the onboard controller for boot, which is hda+hdc, so
the promise drives become hde and up.

ppps doing a cat /proc/ide/pdc2x shows both interfaces working, and with 2 drives attached -per-
interface. as mentioned above, and show below, only 2 drives of the 4 are found by linux. Im hoping
that we can get it to either find all 4 drives (so i can linux raid0 them) or find one drive, which is
the fasttrack raid (prefered! :P)
