Mckay) Newsgroups: comp.os.386bsd.questions Subject: Strange irq problem/Zoom-250 Date: 22 Jan 1995 15:25:56 -0500 Organization: MIT EE/CS Lines: 16 Message-ID: <3fuf0k$g5j@MICRO-HEART-OF-GOLD.MIT.EDU> NNTP-Posting-Host: micro-heart-of-gold.mit.edu Howdy. I am having a very interesting problem with my FreeBSD 2.0 system and a Zoom-250 Internal modem (ISA). The modem is set for COM3/IRQ5 and when I use DOS the modem works just fine and works well with IRQ5. However when I boot FreeBSD 2.0, the kernel claims the device is "not found" unless I remove the "irq 5" from the kernel config line (I assume this makes it polled) and then it not only can find the device but makes the correct UART identification as well. Any ideas how to make FreeBSD work with IRQ 5 in this case, or what to look at next? Thanks! - Shawn
