PowerBook 2000 + Mouse + 2.4.0-test7

[tom_gall]

Hi All,

 quick question, with a 2.4.0-test7 that was fresh as of last Friday.


 On my PowerBook 2000, the kernel machine checks when it init's the serial ports
and once I redid my config file to remove that support, kernel boots but X no
longer recognizes the trackpad. (Yet on a 2.2.x series with the ibook kernels it
does)  Is this a known problem?

I don't know for Linus test-7, but I can speak for the current state of
bk 2.4-test8

You probably have the "legacy" (dumb) serial ports compiled in. The
Macintosh serial ports are a separate option. The ISA bus doesn't exist,
an nobody answer to legacy IO addresses on a mac, thus causing the
machine check.

Get the bk tree. In the "Macintosh Drivers" option, you can either enable
the ADB HID that comes with the input devices, or the old mac_keyb.c
driver. If you are using the mac_keyb.c driver, then you can also select
the old adbmouse.c driver in "Char devices/Mice). This should allow your
current 2.2.x setup to work.

If you want to switch to the new input layer, then enable the ABD HID.
You'll have to create the appropriate /dev entries for, at least, /dev/
input/mice, and change /dev/usbmouse and /dev/mouse to point to it. You
can safely remove /dev/adbmouse. Note that the old adbmouse driver was
BusMouse protocol while the new input layer provides you with PS/2 datas,
like USB mice.
