Scandium: the retired heavyweight.
October 2004. I look at the site of http://www.nowthatsit. They have a series of extra ordinary computers: Compaq AP400 workstations. With extreme specifications. I fall in love and I order one. I have never been sorry.
These machines are workhorses. They don't give an itch. Compaq used all their skills to hone the performance of these computers to the maximum. I mention the twin CPU, twin 128 MB RAM banks, twin SCSI disks, integrated 5 Watt (RMS, not PMPO!) HiFi mono speaker and a very strong overal design. Check it out on the pages on this site that are completely dedicated to the AP400.

| IP address | 192.168.56.108 | |
| Running since | November 2004 |
Below, you will find the contents of the most important files for Scandium. These files are important for all computers and the settings are extremely hardware dependent. Read the files and use the things you want to try out on your machine. Remember that Scandium is an odd critter running an odd ball Linux. I never figured out how to run it with static IP addresses, so it runs as a DHCP client..

# | Don't forget to run 'lilo' after you make changes to this |

# Specifies the boot device. This is where Lilo installs its boot

# Enable map compaction:
# Tries to merge read requests for adjacent sectors into a single

# Specifies the location of the map file. If MAP is

# Specifies the VGA text mode that should be selected when
# booting. The following values are recognized (case is ignored):
# NORMAL select normal 80x25 text mode.
# EXTENDED select 80x50 text mode. The word EXTENDED can be
# abbreviated to EXT.
# ASK stop and ask for user input (at boot time).
# use the corresponding text mode. A list of available modes
# can be obtained by booting with vga=ask and pressing [Enter].
vga=791
# You can set a password here, and uncomment the 'restricted' lines
# in the image definitions below to make it so that a password must
# be typed to boot anything but a default configuration. If a
# command line is given, other than one specified by an 'append'
# statement in 'lilo.conf', the password will be required, but a
# standard default boot will not require one.
#
# This will, for instance, prevent anyone with access to the
# console from booting with something like 'Linux init=/bin/sh',
# and thus becoming 'root' without proper authorization.
#
# Note that if you really need this type of security, you will
# likely also want to use 'install-mbr' to reconfigure the MBR
# program, as well as set up your BIOS to disallow booting from
# removable disk or CD-ROM, then put a password on getting into the
# BIOS configuration as well. Please RTFM 'install-mbr(8)'.
#
# password=tatercounter2000
# You can put a customized boot message up if you like. If you use
# 'prompt', and this computer may need to reboot unattended, you
# must specify a 'timeout', or it will sit there forever waiting
# for a keypress. 'single-key' goes with the 'alias' lines in the
# 'image' configurations below. eg: You can press '1' to boot
# 'Linux', '2' to boot 'LinuxOLD', if you uncomment the 'alias'.

Synopsis
OK, now I told just about anything that is specific and that can be hairy when your machine will not boot upto an inlog prompt. If your system uses a comparable Linux, these settings might help.
System settings are so machine specific that I cannot help you, unless you happen to live around the corner. If that is the case, this magic number '5012' should ring a bell. If the number is just a number to you, please find someone near your place to help you out.
