I just tried to install sarge, using the pre-rc2 debian-installer, on
an eMachines T1742 Celeron 1.7 GHz desktop system (82845G/GL
[Brookdale-G] mainboard chipset). After installing the base system,
the floppy drive, network card, and sound card do not work. Although
they are supported hardware, there appear to be numerous irq conflicts
(these devices sharing irq 1 with the keyboard) and possibly memory
conflicts. I have included below some output showing the symptoms.
Note that I have the same problems when trying Knoppix 3.2 in this
box. This seems to be a major compatibility failure. Any advice on
where to go from here? (ie try to fix it, go to kernel or developer's
mailing lists, give up and get a new computer?)
