incorrect milo image for XL 366

I installed RedHat 7.0 on an Alpha XL 366. The XL 366 does not have an SRM
console. It only has AlphaBios available. Therefore the only option is
to boot from milo.
Following the table on page 89 of the "Redhat installation guide for the
alpha processor" that was distributed in the RedHat 7.0 for Alpha box, I
made a disk based on "xlt.img". This table specifically says to use
xlt.img for the XL-366.
When I booted the floppy (following the rest of the instructions from
Appendix A in the installation guide), linload.exe loaded milo from the
floppy as it should have. However, milo froze after it printed "Switching
to PALcode 0x0...". I tried this several times and also tried using
the "xl.img". Neither one of them worked as specified in the installation
guide. All of them froze after printing "Switching to PALcode at 0x0...".
I was able to get the correct milo image from a Compaq internal site, and
then the boot went fine. RedHat is now installed on the system.
Page 90 of the installation guide states to visit this site for the milo
That site contains an XL-366 directory, but its only contents are a file
labeled "milo" that is 0 bytes long.
All of the above description can be summarized by saying that either
the "installation guide for the alpha processor" wrongly tells us to use
xlt.img, or the Redhat 7.0 CD does not contain any milo images capable of
running on the Alpha XL-366.
Steps to Reproduce:
1. Build a milo disk from the RedHat 7.0 Alpha cd by typing:
cp xlt.img.gz .
dd if=xlt.img of=/dev/fd0 bs=72k (found on p. 103 of the installation
2. Insert the floppy into the floppy drive of an Alpha XL-366
3. Push the XL-366 power button
4. Press 'F2' for setup
5. Follow the instructions on page 94 of the installation guide to set up
an OS selection that will boot the milo floppy
6. Press 'Esc Esc' to go to the OS selection menu
7. Boot the Milo floppy by selecting it from the OS Selection menu
Actual Results: linload.exe will load milo, which will then freeze after
"Switching to PALcode at 0x0...."
Expected Results: After seeing "Switching to PALcode at 0x0....", the
milo prompt should have appeared so that we could boot RedHat from the CD
I re-read my bug description, and realized I forgot to say that if necessary, I
am able to send the correct milo image I obtained from a Compaq internal site.
I could not find this image on external sites, so it may only be available on
the internal site.
In addition, I will check this bug report frequently so that the redhat
developer may ask me questions.
Milo is officially unsupported 8/ however I'll see what can be done
