I'm trying to install 2.0.5R onto a Gateway 2000 machine. It has a
Micronics motherboard, and is a 486DX2/66 with 32 Mb of RAM. It ran
1.1.5.1 just fine. I've installed 2.0.5R once already from the same disks
w/o any problem. The only hardware in the system is the SMC Ethernet
device and a Mach32 (VLB) graphics adapter.
When booting from the updated boot floppy (the one with the 4MB RAM fix), I
tell the kernel to boot with the '-c' option. I then set the port, irq,
and iomem of ed0 to 0x300, 10, and 0xcc000, which is the same as my jumpers
are configured for. When I initiate a 'probe ed0', I always get:
Fatal trap 12: page fault while in kernel mod
fault virtual address = 0xefc00330
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf019d467
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 0 ()
interrupt mask = net tty bio
It will get as far as the installation menus when I disable all the
non-relevant devices (I always disable the devices that I don't have
installed). I've read the FAQ, and I've been installing FreeBSD since the
1.0 days. I can't figure this one out.
Help? What is the deal here?
