I have a DELL 5100/2SP running SCO 3.2.4. and MPX 3.0. Both processors
are serialized. The only non-DELL card in the system is an Equinox
MEGAPORT card. I'm using the latest drivers. A brief description of the
card is given below.
I have a strange timing problem. sometimes (but not always) when I
re-boot, the time advances at almost double the normal rate. The time is
always correct on boot up and the hardware clock is keeping prpoer time
(I check with cat /dev/clock). However the software clock is way out. At
other times after a re-boot, the system is normal.
I don't understand how SCO determines the time and if I did I might be
able to understand the problem. What could cause SCO to calculate the
The other strange thing is that after a shutdown, and after the message
"Safe to power of or press any key to reboot", if a key IS pressed the
screen just blanks and a hard boot is nexeccary. All other behaviour
I suspect the MULTIPORT card as the hardware is OK... or it SEEMS OK>
I don't know what to do next, short of replacing the card.
Any suggestions would be welcome. The system is heavily used so I can't be
messing around with it by removing the card for a while to test the card
Following is info on the card I got from Equinox in answer to some questions.
The Megaport board when used in a EISA machine needs to have the PA0
jumper installed. This jumper is located at the top of the board on
the component side. The jumper goes between the middle and upper pins
on PA0 ..... let me know if you cannot find it.
This will hard code the address of the Megaport at 340/341 for dual
port addressing. It should work for you now.
You also should try to install the Megaport board in low memory...
between 640k and 1024k ..OK????
You need an eisa config utility for every eisa computer. Dell should
be able to help you with that. Once the PA0 jumper is installed on
the Megaport board... the computer will no longer ask you for a
eisa-config file for it. The EISA Config utility is only needed when
you set up the computer the first time... however every eisa board
that you place in the eisa slot..... needs an eisa-config file. This
is usually supplied by the manufacture of the board. Since the
Megaport board is really an ISA board.... it does not have an
eisa-config file..... the PA0 jumper simply tricks the computer into
thinking that it is on the motherboard.
