I had nothing but grief trying to make The Vaio Z600 muxes everything on IRQ 9. The PCMCIA device did not support IRQ 9. Windows 2000 was able to route IRQ 7 as an ISA function interrupt which allows it to support the device. FreeBSD did not; and I was in a hurry to get my code written. The RL5C475 is still using PCI for the CSC interrupt. More later... BMS To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
