Kernel: FreeBSD bogushost2 5.1-CURRENT FreeBSD 5.1-CURRENT #0: Sat Jul 19 23:38:13 EDT 2003 root@bogushost2:/usr/obj/usr/src/sys/ARL5KERNEL i386 Since I kept on getting "stray irq 7"'s with my laserjet 4, I decided to set my parallel port to use polled mode at boottime. While I guess I could add a special script in /usr/local/etc/rc.d to run 'lptcontrol -p', this sucks because it doesn't exit if the printer isn't on, even though it works otherwise. So I added to /boot/device.hints the following three lines: hint.ppc.0.at="isa" # hint.ppc.0.irq="7" hint.ppc.0.flags="0x20" According to the manual setting bit 4 of the flag to one should set it to polling mode, but it doesn't work. I know for a fact that the loader is reading the hints file, too. Here's dmesg: ppc0 port 0x778-0x77f,0x378-0x37f irq 7 drq 3 on acpi0 ppc0: SMC-like chipset (ECP/EPP/PS2/NIBBLE) in COMPATIBLE mode ppc0: FIFO with 16/16/9 bytes threshold ppbus0: <Parallel port bus> on ppc0 lpt0: <Printer> on ppbus0 lpt0: Interrupt-driven port Is there something that I overlooked? Thanks, Andrew Lankford PS Apart from some annoyances with ghostscript ps to pcl translation, nothing beats a vintage HP laser printer :)
