Hello

Im trying to use more than 10 ide controllers on a 2.4.26 kernel and i
did not succeed.

i patched already according to several posts (Alan Cox) so now i get :

PDC20269: ROM enabled at 0xfdee0000
~    idea: BM-DMA at 0xdf50-0xdf57, BIOS settings: hdu:pio, hdv:pio
~    ideb: BM-DMA at 0xdf58-0xdf5f, BIOS settings: hdw:pio, hdx:pio

but unfortunately :

ide1 at 0x170-0x177,0x376 on irq 15
ide3 at 0xdfa0-0xdfa7,0xdfaa on irq 23
ideb: UNABLE TO GET MAJOR NUMBER 0

i guess i need to patch major and minor numbers for the devices as well
but i did not reach to.

i search into Documentation/devices.txt without sucess.

Does anyone know what are major/minors for hdu, hdv, hdw, hdx ?

Thks a lot for your help.

not being a professional, i see:

evil@sheep:~$ la /dev/hd?
brw-rw----    1 root     disk       3,   0 2004-03-10 11:33 /dev/hda
brw-rw----    1 root     disk       3,  64 2004-03-10 11:33 /dev/hdb
brw-rw----    1 root     disk      22,   0 2004-03-10 11:33 /dev/hdc
brw-rw----    1 root     disk      22,  64 2004-03-10 11:33 /dev/hdd
brw-rw----    1 root     disk      33,   0 2004-03-10 11:40 /dev/hde
brw-rw----    1 root     disk      33,  64 2004-03-10 11:40 /dev/hdf
brw-rw----    1 root     disk      34,   0 2004-03-10 11:40 /dev/hdg
brw-rw----    1 root     disk      34,  64 2004-03-10 11:40 /dev/hdh

so, it's a major number for every controller (e.g. "22" for hdc+hdd each
belonging to one controller). hdi+hdj would be major 35, minor [0|64] ?
i'd try this out for hdx and further...

did you try devfs/udev? perhaps it could solve this by itsself....?

PS: maybe Documentation/devices.txt helps out too.

afaik even the 2.6.x kernel defines only 10 major numbers for IDE 
devices (from 0 upto 9). All are predefined - see include/linux/major.h
