System:
1) On-board IDE (no connections)
2) MegaRAID 1200 (external array under construction; no connections at this time)
3) BusLogic 958
* 4.3G U+W drives = /dev/sda, /dev/sdb, /dev/sdc
* PD/CD = /dev/sdd, /dev/cdrom
* CD-RW = /dev/sg0, /dev/cdrom1
* ADR tape = /dev/nst0
* DAT tape = /dev/nst1
4) Promise-100
* 60G UDMA100 Maxtor = /dev/hde
I want to boot from /dev/hde, and but IDE/SCSI mix confuses things. If I
understood LILO's ability to explicitly reorder the BIOS disk discovery order,
I'd probably be able to get it to work the way I want it. But I don't.

Apparently doesn't copy correct ramdisk, kernel, or whatever onto the boot disk.
Result is boot-time kernel panic. Can't tell you details at this time (I'm at
work). Also, the mkbootdisk text equiv doesn't support vga= settings, so I can't
specify VESA framebuffer modes.

Yes. I make them using same command line params I've always used to build ram
disks for SCSI. Dasy to do. Filesizes of mine are consistent with working
version initrds.

Haven't checked that, but also haven't seen mkbootdisk fail to copy them
correctly in the past.

Present "Red Hat Way" is to modularize everything. Ergo, mkinitrd even for IDE.

I've been unable to locate a grub source not filled with dire warnings. Is it
ready for prime time?
