Subject: readw() access
Date: Wed, 1 Aug 2001 22:33:44 +0200 [thread overview]

Hello,
I'm trying to port a driver from 2.2.x to 2.4.x where I previously has used
readw() to read the contents of the memory-adresses 0x408-0x40c (Where the
BIOS gives you the adr. for the par-ports.) But on 2.4.x readw(0x408) Oops:
"Unable to handle kernel NULL pointer dereference at virtual address
00000408"
How do you read a memory-address like this?
