Subject: 3c589 on a thinkpad 701
Date: Mon, 18 Dec 1995 15:32:05 -0500 [thread overview]
Message-ID: <19951218203205.XO8VWvOuXLb-lZKL8vBzUXlnedDWS8MJ_uQeJmQxwdw@z> (raw)
the quick hack to get the 3c589 (and presumably almost
anything else) to work on the thinkpad was to change
p = (uchar*)(KZERO+0xC8000);
in /sys/src/9/pc/main.c to
p = (uchar*)(KZERO+0xD0000);
i'll work out something more general later.
the problem is that 0xC8000 appears to be writable (it's probably shadowing
something), but nothing else can be mapped over it.
i couldn't find a configuration control screen to enable or disable shadowing.
does anyone happen to know
- which sound chip is used in the 701?
- which infrared chipset is used for the irDA interface?
