I've spent the last couple of days tracking down a problem starting X on a Dell Inspiron 5100. I've got as far as discovering that the video BIOS is not being completely mapped: it's 60 kB long, but only 48 kB are being mapped into memory. To make matters worse, the machine doesn't have a serial port, so I can't apply a kernel debugger to find out what's going on. Can anybody point me in the right direction? Where should I be looking for this? Is this memory mapped permanently, or is it only during X startup? Greg -- See complete headers for address and phone numbers
