- In the event that someone is keeping score, or for those "Inquiring
- minds.." that "..want to know," I installed LILO ver 6 this week with
- the following configuration:
-
- /dev/hda4 SCO ODT 2.0/System V Rel 3.2v4 (330 megs)
- (no other OS' installed this drive & LILO installed as the MBR)
-
- /dev/hdb1 Linux 0.98.pl1 Minix Root Partition (64 megs)
- /dev/hdb2 Swap (8 megs)
- /dev/hdb3 Extended File System (120 megs)
- /dev/hdb4 SCO eafs (Extended Acer File System) 400 megs
-
- The disk configuration is 2 ESDI drives: 330 MB Micropolis and
- a 660 MB Maxtor using a WD1007V controller.
-
- Rest of system is a 16 Meg 486-33 ISA Micronics motherboard in some
- REALLY ugly hand-me-down tower box!!
-
- Note that this is with *NO* Linux installed on /dev/hda, using LILO as
- the MBR (Master Boot Record) and mounting /dev/hdb1 (2nd drive) as
- root for Linux. I took the liberty of setting a small delay in the
- install script (-d 30) to give one a chance to hit a shift key since
- my system wants to complain if you hit a key too early in the boot
- sequence and it immediately reads the 1st drive after POST tests are
- done (I've configured my CMOS settings to boot first from the hard
- drive as a half hearted security measure - this I change alot when
- fooling around with Linux upgrades ;-) This configuration will boot
- the 1st configured OS in the install script, which in this case is
- SCO:
-
- $ROOT/etc/lilo/lilo -b /dev/hda -c -d 30 -i /etc/lilo/boot.b $* \
- sco=/etc/lilo/chain.b+/dev/hda4@/dev/hda \
- /linux \
- /linux.backup
-
- Note that I renamed the ``Image'' files in the root directory to
- ``linux'' and ``linux.backup'' respectively. I didn't do this because
- the LILO examples did it this way, but rather, because I like my OS
- load modules to say what they are. This is strickly a personal
- preference and does not change anything! You should be aware that the
- Makefiles that recompile the source will name the the result
- ``Image'', not ``linux''. The are not automatically moved to the
- root directory, either.
-
- What I haven't tried yet is what happens if that partition isn't
- marked active - would it go on to the next configuration? I kinda
- doubt it from my read of the documentation. At least not perhaps
- without Linux being installed in a small starter partition on
- /dev/hda that would itself have to be marked active.
-
- Which reminds me. Is anyone working on doing an Acer or Extended Acer
- file system for Linux? Sure would make my life easier since I earn my
- living supporting SCO systems (but, in truth, absolutely worship the
- ground Torvalds Linus walks on for his creation.)
-
- Also, if we had a COFF object file loader, having commercial software
- available for Linux would cease to be a problem. I have consistently
- run binaries that were linked, say for SCO, on ISC and Esix for
- example as well as any other way around. Really, the only time I seem
- to get in trouble is with the differences between the various ``pty''
- implementations. I want to believe that this would be possible with
- Linux. Did I not read a message where Xenix ``a.out'' (actually,
- x.out) format was supported now? I hope that means that the system
- call interface was reasonable and that the same could be expected of
- SCO Unix. What about the ``kludge'' we had with gcc a few years back
- known as ``COFF encapsulation''? Perhaps that might be a place to
- start.
-
- Yea, I know, I can just hear it now, "If you're so good at finding
- things that need to be done, why don't you do it yourself?" Believe
- me, if I thought I could, I would -- go ya one better: If the file system
- Maven (Remy Card?) wants to give me some pointers or if he needs to have
- structures of the superblock/inode stuff, I'm your man.
-
- Well, this started out as a short announcement in the hope that it would
- encourage some of the faint at heart out there. It has instead, turned
- into a soapbox from which I have declared Yet Another Linux Project
- er, YALP, as in yacc, and such was not my intent. But whatta ya think
- out there - is this something we need to be about? Volunteers accepted,
- BTW.
-
- All the best to LinuxLand, pappy
