- Hard Disk Drives
The new Motherboard only
supports 1 hard disk drive.
- Switches
Many of the switches have been
relocated (see attached diagram), the sticker on top of the power supply reflects the new
positions.
Disabling on-board video is now simplified to Switch 8 on block SW10
only.
Link 5 is a connection to the battery just in case you need to drain the
CMOS.
SW5 which controls the Colour or Mono setting for the on-board video
will always be set to Colour. This switch does NOT need altering if you put a paper-white
monitor on the system. The switch is for unknown software that may look at this register
for it's settings.
- Networking
Thick and thin Ethernet plugs will be
fitted on all machines. For the PC range that does not have on-board Ethernet, the
following components; IC75,IC98, IC97, IC88 and TX1; will be removed.
Venus II will be supplied with 1.2.16 ROM BIOS, these are NOT the same
ROMs as the previous XEN-S boards. There will now be 4 sets of ROMs for the XEN-S range,
| (1) XEN-S (Venus I) |
| (2) XEN-S (Venus I) Novell Remote Boot |
| (3) XEN-S (Venus II) |
| (4) XEN-S (Venus II) Novell Remote Boot.* |
| * All but (4) are currently available. |
- Memory Expansion
Support for the 1, 2 and 4MB
memory modules will continue as before.
- Documentation
The In-The-Box manuals will
consist of the current manuals plus a fly-sheet explaining the differences in the manual.
The fly sheet and sticker on the Power Supply both refer to clock speed
settings of 10 and 20MHz, these functions are NOT currently supported.
The 80287 and 80387SX Co-processor installation notes refer to the
original XEN-S (Venus I) motherboard and are incorrect when referring to the position of
the sockets. The PAL chip for the 80387SX remains in IC96 but the location is different.
The location for the 80287 and the 80387SX processors are detailed on the top of the power
supply.
