Find Bit
Find Bit works on the software model but not in the actual hardware. The operation returns zero
when a non-zero result is expected.
; Demonstration of find_bset_with_mask erratum
;
; The data register is loaded with all 1’s
; Then we do a find_bset_with_mask with a mask of 0x10,
; which should find bit 4 as the first bit set.
; On hardware, the result comes back as zero indicating no bit set.

Wrong Find Bit.
Do not use the FIND_BSET_WITH_MASK instruction with an immediate mask operand.
NoFix
66 MHz Capable Bit
The IXP1200 is 66 MHz capable, but the 66 MHz Capable Bit (bit 21) in the PCI_CMD_STAT
register is incorrectly fixed to zero indicating that it is not capable of 66 MHz operation.
When this bit is read, the IXP1200 incorrectly indicates that it is not capable of operating at 66
MHz as defined in the PCI Local Bus Specification, Revision 2.2.
Do not use this bit for determining the maximum operating frequency of the IXP1200’s PCI bus.
NoFix.
