No, you're wrong. Unless you've got APIC running, if your Linux box is x86, you're still carrying baggage from 1981. Namely, the limited number of IRQs. This problem has been mitigated over the years, first, partially, sometimes, after much waving of Dead Chickens, by Plug-n-Pray, and then by PCI, and then by OSs that allow IRQ-sharing. Even then, though, the Dead Hand Of 1981 hangs over Linux: perform- ance suffers if too many PCI devices (whether cards or devices built onto the mobo: IDE, USB, ieee1394, SCSI) share the same IRQ. -- ----------------------------------------------------------------- Ron Johnson, Jr. [EMAIL PROTECTED] Jefferson, LA USA Spit in one hand, and wish for peace in the other.
