Hi Linux experts,
I try to boot linux via loadlin from Win95 to get sound support as
described in http://www.screamin.demon.co.uk/mwave.html for my
ThinkPad 760ED.
Unfortunatly when i try to boot via loadlin linux crashes with a
general protection (fault): '0000'. (more info below)
Playing around a bit i discovered that the problem actually is APM. if
i take a kernel without APM enabled (e.g slackware-3.4 kernel/bare.i,
linux 2.0.30) it works but not then APM is enabled (e.g slackware-3.4
kernel/bareapm.i, linux 2.0.30 as well as self-made kernels for
2.0.28/2.0.33 (see http://www.zurich.ibm.com/~sti/chiggiogna/linux/system/kernel/2.0.33.html)!
i also noticed that the APM reports during the bootin (and immediatly
before crashing) a different 'dseg' address, namely '20a' instead of
the usual '9fc0'.
does anybody have an idea how to fix that ?
regards
