Hi,
What I did:
You need
1) NFS server with copy of redhat cdrom :o(
2) get patches & tools from dandelion
3) compile a kernel with DAC960 in it, execute litt'l script to
create device inodes on compile machine
4) copy this kernel on RH5.2 bootdisk ( compile hard just NIC,
DAC960 - smallest possible or it won't fit
onto floppy ( I got around it using superformat in 1.8Mb floppy)) as
vmlinuz
5) on RH5.2 nfs export, replace all occurences of fdisk & lilo with
the one from dandelion
6) on RH5.2 nfs export , create a dir DAC, containing :
<---SNIP--->
lib/modules/2.0.36/ well here all modules...
boot/vmlinuz.dac
dev/rd/c0d0....c1d7p7 U can create more if U want...AFAIK Midnigt
Commander is a marvelous tool
sbin/fdisk & lilo from dandelion
etc/fstab & lilo.conf ( handcrafted....)
<---SNAP--->
etc/fstab (for me anyway)
<---SNIP--->
# Manually added !
/dev/rd/c0d0p1 swap swap defaults 1 1
/dev/rd/c0d1p1 / ext2 defaults 1 1
/dev/rd/c0d1p2 /usr ext2 defaults 1 2
/dev/rd/c0d1p5 /tmp ext2 defaults 1 2
/dev/rd/c0d1p6 /var ext2 defaults 1 2
/dev/rd/c0d1p7 /home ext2 defaults 1 2
<---SNAP--->
etc/lilo.conf (also for me ;o)
<---SNIP--->
boot=/dev/rd/c0d0
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
append="linear"
default=linux
image=/boot/vmlinuz.dac
label=linux
root=/dev/rd/c0d1p1
read-only
<---SNAP--->
OK Here we go....boot your floppy, check if NIC recognized & DAC...
1) NFS install... you know, RTFM ;-)
2) Need to get to 2nd stage install, once there, DON'T GO ANY
FURTHER !
3) ALT-F2 Yahoooooo, a prompt !
Let's kludge a little for now....
1) We need Device files
2) Let's say you have created with DAC BIOS 2 RAID 5 logical disks
(I did) One for swap, other for the
rest... (small swap, big rest)
3) Swap would be /dev/rd/c0d0p1 ( one whole part on Controller 0,
Disk 0, Partition1)
4) The other logical DAC Disk I'll use for data & other partitions
SO....
5) at our holy prompt we create needed device inodes....
6) mknod /tmp/c0d0 b 48 0
7) mknod /tmp/c0d0p1 b 48 1
8) When now you do fdisk /tmp/c0d0 , U can create a partition ( for
me 120Mb) and tag it as swap
<---SNIP--->
fdisk /tmp/c0d0
Command (m for help): p
Disk /tmp/c0d0: 128 heads, 32 sectors, 64 cylinders
Units = cylinders of 4096 * 512 bytes
Device Boot Start End Blocks Id System
/tmp/c0d01 1 64 131056 82 Linux swap
<---SNAP--->
I wrote the config , of course :o)
9) create device inodes for the rest.... (partitions for / , /var,
/tmp, /usr, /home....etc,etc)
10) like 6 , first the disk, mknod /tmp/c0d1 b 48 8
11) U have 7 more possibilities ( so 7 partitions...)
12) mknod c0d1p1 b 48 9
13) mknod c0d1p2 b 48 10 etc...etc up till c0d1p7 b 48 15 but only
the one U need
14) fdisk /tmp/c0d1
<---SNIP--->
The number of cylinders for this disk is set to 8660.
This is larger than 1024, and may cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /tmp/c0d1: 128 heads, 32 sectors, 8660 cylinders
Units = cylinders of 4096 * 512 bytes
Device Boot Start End Blocks Id System
/tmp/c0d11 1 51 104432 83 Linux native

/tmp/c0d17 3546 8660 10475504 83 Linux native
W to write partition table (as usual...)
<---SNAP--->
OK , normally U have the needed disks ....
in /tmp/rhimage, U'll find your DAC dir ;o)
15) let's mke2fs & mount what we need
16) mke2fs /tmp/c0d1p1 (and the other cOd1pX)
17) mount -t ext2 /tmp/c0d1p1 /mnt
18) create mount dirs in /mnt ( these will be on the root disk)
19) mkdir /mnt/etc and mkdirs for all your fstab entries...on /mnt,
of course
20) mount -t ext2 /tmp/c0d1p2 /mnt/usr ...etc, etc for all your
fstabs
Here U get back to ALT-F1
1) Skip SCSI
2) skip swap
3) in short get to software install
4) select your software
5) install
6) configure
7) at the end: DO NOT I REPEAT, DO NOT REBOOT !!!!!
get back to your prompt ALT-F2
cd /tmp/rhimage/DAC (your fstab, lilo.conf, device inodes, fdisk, lilo,
kernel, modules)
/mnt/usr/bin/find . | cpio -pdv /mnt/
this copies your carefully prepared (and necessary files) onto your
root fs
lilo -r /mnt
umount all /mnt/*
umount /mnt
push your reset button, get this floppy out
Took me 3 hours to install (compilation included) When I find some time,
I'll kludge this in RH install disk
did the same in 1 day for 6 other pc's
Have to say: Mylex & driver together are extremely robust and FAAAAAST!

Hope this helps (a little)
