You might prefer to ask for help to a Linux/Alpha mailing list, such as
<axp-list@redhat.com> --sometimes referred to as "the axp list"--, or
<linux-alpha@vger.rutgers.edu>. As far as I know, these lists are not devoted
to Linux and Alpha hackers. However, if you subscribe to the 1st of these
lists, you should be prepared to get 10-100 emails a day!

My personal opinion is that there are Linux/ix86 distributions that are more
stable that the today [July-96] Linux/Alpha distributions; so, especially if
you're a Linux neophyte (like me), you might consider to install Linux first
on an Intel-based platform: you would get something like a "reference Linux
platform" (this does not mean that it would be 100% bug-free...).

Congratulations: you seem to get Linux/Alpha installed... it's sometimes a
paintful process.

The device names, e.g., the /dev/* for disk and CDrom drives, vary from one
Unix(-like) implementation to another... moreover, they (often at least) vary
according to the type of i/o controller on which such drives are attached
(e.g., scsi controller vs ide controller for "traditional" Linuxes). **If* you
installed a Linux/Alpha distribution from Red Hat --which seems to be the most
widely used Linux/Alpha distribution today--, you should get & read
installation guidelines from Red Hat. I suppose that the less risky method is
to buy a regular licence to this company, since it would give you the ability
to get support... unambiguously! [As far as I am concerned, I did not
installed Red Hat Linux.]
If you're ready to play in a "more ambiguous" mode, you can use the following
informations that I received after *freely* subscribing to

We just purchased a Multia and are trying to install RedHat off of
Infomagic's April edition. We have encountered a slight problem. So far,
we have gotten the box to load MILO and boot from a boot disk and ramdisk.
When install is run, the CD will not mount locally because the source files
are in a different location on Infomagic's CD than on Redhat's. Any idead
on how to make this thing work? Thanks!

Thanks for the pinouts. Turns out its the same --- or at least close enough
(I didn't check every pin) as the Sun splitter cables; just used a F-F gender
bender (the host end of the Sun splitter is M), then a Radio Shack M-DB9 <->
M-DB25, then my HP 200LX serial cable, pulled in lxtools and typed "make", and
vavoom, 115kbps backups! Yea!

This is just too wonderful. I can't get over what a marvelous toy this thingie
is. Bought an "easy WebServer", still in the original DEC box, from a friend.
Loaded Red Hat 3.0.3 on it without too much pain (would have been easier if
I'd waited a couple of weeks for that lovely note from Stephen Gaudet "Loading
a UDB with Red HAT 3.0.3"). Yea, there were some rough spots --- I still
haven't figured out what provokes crond into mugging the CPU, for instance ---
but it's basically working well enough to be a joy rather than a pain.

Sorry, but you must pay full price or download it over the net for free. We
aren't making a windfall on Linux/Alpha, and we can't afford to sell it
for much less then we do. That's why we give it away.

Having just returned to the alphas after a longish time away I am a
tad confused (and frustrated) by the SCSI situation...

I have a noname, I'm putting on several (!) Quantum Grand Prix 4.3 GB
disks (its going to be a big web cache), so I got my trusty RH 2.1
CD-ROM and tried and install, which seemed to work OK. The system
had a 1.3.66 MILO on it, and the redhat 2.1 default kernel. When
the thing booted it set the drives to async SCSI and then loused up
handling the root mount completely - and with 2 drives installed it
got completely confused, losing SCSI commands all over the shop.

I then replaced the MILO with Dave Ruslings latest and greatest
(around 1.3.99), and the kernel with a 2.0.7 compiled with sync SCSI
only. That works OK.

With the current distributed kernel, whats safe to compile in for a
noname with NCR8xx on-board SCSI? What gives the best real
performance? Any other comments on the best way out of this...?

Thanks
Nigel.

I have the 233 version and I think it is a very decent machine. The
packaging is great. The performance of the 166 mhz. unit would be
somewhere between that of a 75 Mhz. pentium and a 100Mhz one.

As for its discontinuance being a problem, that is hard to say, but if
it were me I would grab one while I could as the price is unbeatable.

Just get an external SCSI drive and a cable and you will be all set,
the connector is on the rear of the unit.

Not very - but if you want to install from CD you will have to get an
external scsi CDROM drive.

Hmm, if that FUJITSU disk is extra big (> 2Gb), you might have some problems.

But did you reboot *after* partitioning the disk, before continuing with the
install? THIS IS OFTEN NECESSARY, AND ALWAYS A GOOD PRECAUTION!!!

Yes, I know it's a pain to have to go through the three floppies all over
again, but it seems the only safe way to ensure that the kernel knows the
new partition information.

Heck no. The current plan is to leave a 2 MB (or so) DOS partition as the
first partition on your drive. You then put linload.exe and milo onto that
dos partition and use ARC to boot MILO from the hard drive, and then use
MILO to boot Linux.

I'm do that on a couple of machines, and it's no worse then flashing milo
and a heck of a lot safer.

What do you intend to do by typing "cd /cdrom" ? To be ready to read files
that are on a CDrom you've inserted in the CDrom drive unit, e.g. to use "ls"
for listing them ? If so, typing a "mount" command might be, or not, useful:
there are variants in the layout of informations on CDroms, it's the same for
floppies, e.g. there are "DOS floppies", "Linux-mountable" floppies (with
possibly imcompatible file layouts)... and many more! So I cannot help you
very much, but after reading some documentations (see below) you should soon
be able to find your way by yourself.
