Hi,
I have been asked to look at a legacy Tornado 1 system which boots from a DiskOnChip to see if this can be changed to boot from a compact flash disk. The compact flash is on the primary channel of the *second* IDE controller.
I dont understand the boot line:
"#define DEFAULT_BOOT_LINE "ide=0,0(0,0)host: ..........."
Where is this documented? What are the 0,0's? I presume I have to change one of them to say I am using the first disk on the second channel?
I have looked at the documentation for ideDrv() and as a result changed IDE_INT_LV to 0x0f in pc.h to take into account that I am using the second IDE controller which defaults to IRQ 15 in the bios.
I am confused by some of the documented ide functions which state the disk parameter can only be 0 or 1. The primary disk on the second IDE controller could be considered to be disk number 2. Does VxWorks/Tornado 1 support two IDE drivers?
Thanks for any input.
