You shouldn't need to have Penguin warm up the serial ports if you are using Linux 3.14 (though it doesn't hurt). It just causes MacOS to open its serial driver so as to initialize the SCC chip. Linux configures the SCC chip correctly these days. But warming up the serial ports is still useful on PowerBooks because they have some other circuitry which also needs to be configured and Linux doesn't do so. This means is that the baud rate settings in Penguin aren't relevant. By default, Linux will use 38400 baud, 8 data bits, no parity, 1 stop bit. I usually test a new serial link with ZTerm or ClarisWorks at the MacOS end and picocom or minicom at the other end. When everything works with 38400 8n1 then I boot Linux. The serial console is particularly useful on PowerBook 1XX models because ADB doesn't work. You need "console=ttyS0" on the kernel command line for that. ADB works on the Performa 630, so if you want to use the framebuffer console and ADB, whilst logging all kernel output using the serial port, you'd want "console=ttyS0 console=tty" on the kernel command line. > > > > > > > > > If anyone has a working kernel for Penguin to boot into the base.cow, I > > > would love them eternally. > > > > What sort of Mac are you using?

I would check the mask set revision printed on the chip package. I've never seen a PGA package MC68LC040 chip with the correct mask set so I'm a bit skeptical.

Great, thanks. There's plenty to do. -- -- To UNSUBSCRIBE, email to debian-68k-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
