Bug 14960

The status now is that the controller is detected:

in ida.c I changed
________________this:_____________________

  if (dev->id_iobase) {
    /* check out the configured iobase if given one */
    slot = dev->id_iobase / 0x1000;
    if (slot == 0 || slot > MAX_EISA_SLOT) {

______________into this:____________________________________________

  if (dev->id_iobase) {
    /* check out the configured iobase if given one */
    slot = 6;
/* dev->id_iobase / 0x1000; */
    if (slot == 0 || slot > MAX_EISA_SLOT) {


_____________meaning:______________________________________________
My eisa smart array adapter is in eisa slot 6, look no further.
as far as I see the code then has no problem determining the portaddress
and irq.

_________this is the boot output:___________________________________

____ ida0: irq with no handler__________________
this one is a mystery to me, in the visual kernel config under the
miscelanious section there are 2 ida0 entries so the 2nd one must be the
one this warning is about.

______more info_______________________________
I essentially defined the following as well

options         IDA_CUCKOO_MODE=0

this I had to do because if I didn't my machine would do a trap12
right after detecting the array adapter.


By essentially I mean that when I added it to my kernel config file (CPQ)
the make depend action came with the following error:

File CPQ saved.

Removing old directory ../../compile/CPQ:  Done.
CPQ:96: unknown option "IDA_CUCKOO_MODE"
Don't forget to do a ``make depend''
Kernel build directory is ../../compile/CPQ

___________how I solved this problem_______________
I changed another bit of code in ida.c

________________this:____________________________
/* IDA wdc vector stealing (cuckoo) control */
#define IDA_CUCKOO_NEVER 0              /* never steal wdc vectors */
#define IDA_CUCKOO_ROOTWD 1             /* steal iff rootdev is wd device */ 
#define IDA_CUCKOO_ROOTNOTIDA 2         /* steal if rootdev not ida device
*/
#define IDA_CUCKOO_ALWAYS 3             /* always steal wdc vectors */

#ifndef IDA_CUCKOO_MODE
#define IDA_CUCKOO_MODE IDA_CUCKOO_ALWAYS
#endif


________________into this:_____________________ 
/* IDA wdc vector stealing (cuckoo) control */
#define IDA_CUCKOO_NEVER 0              /* never steal wdc vectors */
#define IDA_CUCKOO_ROOTWD 1             /* steal iff rootdev is wd device */
#define IDA_CUCKOO_ROOTNOTIDA 2         /* steal if rootdev not ida device */
#define IDA_CUCKOO_ALWAYS 3             /* always steal wdc vectors */

#ifndef IDA_CUCKOO_MODE
#define IDA_CUCKOO_MODE IDA_CUCKOO_NEVER
/* IDA_CUCKOO_ALWAYS */
#endif

________________now there's more___________________________________
no ida or id devices are in /dev

I can't make them with MAKEDEV

How do I make them. Now my controller is found I'd like to use the storage
space;)

State Changed
From-To: open->closed

IDA driver in CURRENT will work with EISA controllers now.
