🎀 az(4) — Aztech/PackardBell radio card device driver 🎀

okay bestie, welcome to the az(4) page from the Kernel Interfaces Manual ✨ this one is all about the Aztech/PackardBell radio card device driver, and it is lowkey iconic 💅

🌸 NAME 🌸

az — Aztech/PackardBell radio card device driver 🫶

✨ SYNOPSIS ✨

az0    at isa? port 0x350
az1    at isa? port 0x358
radio* at az?

💖 DESCRIPTION 💖

The az driver provides support for the Aztech/PackardBell radio cards, periodt 🎀

The Aztech/PackardBell cards are stereo FM tuners that allow tuning in the 87.5-108.0 MHz range. They are capable of reporting signal status (tuned/not tuned, stereo/mono signal) and forcing audio output to mono. yes bestie, it really said all that 😌

The Aztech cards use only one I/O port. The I/O port is set by the driver to the value specified in the configuration file. The I/O port must be one of 0x350 and 0x358 — those are the only two options, no cap 💅

🔥 SEE ALSO 🔥

go look at isa(4) and radio(4) too, bestie 🫶 that's the whole SEE ALSO list ✨

🦋 HISTORY 🦋

The az device driver appeared in OpenBSD 3.0 and NetBSD 1.6. a little throwback moment fr fr 🌈

👑 AUTHORS 👑

The az driver was written by Vladimir Popov and Maxim Tsyplakov. The man page was written by Vladimir Popov. iconic behavior, honestly 🎀

💀 BUGS 💀

bestie, it is impossible to determine to which frequency the card is tuned. Thus, the driver will report an internally stored value even if it is not correct (changed by some program that uses direct port access). this one is a real caveat, not a drill 😭
