I already have the firmware on initrd - pulled from /lib/firmware on the main disk, which was built using the mentioned qlogic firmware package. |
| 2 |
So, I'm guessing I'm just missing the udev stuff then...hmm.... |
| 3 |
|
| 4 |
Quick question - how does mdev and udev differ? It seems to be running mdev, which something I came across mentioned that it is a udev replacement seemingly for initrd images. Any how... |
| 5 |
|
| 6 |
how do they differ? |
| 7 |
|
| 8 |
And could I just pull the udev files from the main disk to do the work? |
| 9 |
|

I really hope I can get this working sometime on Friday - that's my last day for being able to get this system working. |

TIA, |

P.S. Sorry, I would have replied in-line, but the new Yahoo! interface is a real pain for replies. |

Ben, |
| 60 |
|
| 61 |
you're almost there. Get the binary firmware from |
| 62 |
ftp://ftp.qlogic.com/outgoing/linux/firmware (just get the .bin files, not |
| 63 |
the .bin-version files). There are five or six files altogether. You don't |
| 64 |
need all, but they are relatively small so it's no big deal putting all of |
| 65 |
them in /lib/firmware. |
| 66 |
|
| 67 |
Make sure on the initramfs you have /etc/udev/rules.d/ with appropriate rules, |
| 68 |
including one to handle firmware loading. Also make sure you have on the |
| 69 |
initramfs /lib/udev/firmware.sh. This script is part of udev. Just copy it. |
| 70 |
|
| 71 |
Then recreate the cpio.gz and try again. My guess is you forgot to include |
| 72 |
the actual firmware. But you're getting very close to a working system :-) |
| 73 |
|
| 74 |
Oh and last but far from least, you need a working /init script on the |
| 75 |
initramfs. All it needs to do is mount /proc, /sys, /dev as a tmpfs, start |
| 76 |
udev, mount the actual rootfs device (as per your silo.conf) and switch_root. |
| 77 |
