[OpenBIOS] Now mounting root

Thanks to your help, I am now mounting root: 

Mounted root (ext2 filesystem) readonly
<4>Freeing unused kernel memory: 52k freed
<4>Warning: unable to open an initial console

Part of the problem was in my PCI config, another problem was I had to
enable the IDE in Linux, as follows: 

#define LINUXBIOS
#ifndef LINUXBIOS
                if (e->reg && (pci_read_config_byte(dev, e->reg, &tmp) ||
(tmp & 
e->mask) != e->val))
                        continue;       /* port not enabled */
#else
        /* force 'em on! */
                if (e->reg) {
                        pci_read_config_byte(dev, e->reg, &tmp);
                        tmp |= e->val;
                        pci_write_config_byte(dev, e->reg, tmp);
                        printk("%s: LINUXBIOS, so Jammed the enable
on!\n", 
                                        d->name);
                }
#endif

So in the LINUXBIOS case you know that no BIOS was there to do things, so
you just turn the IDE on. 

I die on opening the initial console. That's the next barrier to multiuser
boot. Any hints welcome ....  I've attached my .config and the command
line I'm using is:

command_line="root=/dev/hda1 serial=1,9600n8 console=ttyS1,9600";

I have to go back and look, But I think it should be:

command_line="root=/dev/hda1 serial=0,9600n8 console=ttyS0,9600";

Please let me know if you know ...

I'm putting a snapshot on the web page in a few minutes.
