time for another update. following on from the unable to use the modem problem, i had another look.
i booted up the machine. the programs loading on startup are:
ObjectBar 1.60a[b].001
Keyboard Lauchpad 1.00.001
WordWeb 2.1
WindowBlinds
Tab Launchpad
i checked, and the modem didnt work.
so, i unloaded OB, KLP and WordWeb. now the modem works!
so, i rebooted, leaving all of these programs in the startup group.
they all load as expected, and the modem works.
reboot again, just to make sure, and the modem now works.
reboot again, and enter the bios. this is the reason for turning the machine on in the first place. i change the settings from the optimised defaults to the fail safe defaults, save these new settings, and then boot into winXP.
the modem no longer works!!! back to the error message about misconfigured, or already in use
i might ask how changing the bios settings can have this effect, but i wont.
so, since i wanted to get the exact version numbers of OB and KLP i loaded stardock central. this tried to connect to the net 2 or 3 times (bloddy irritating). after i had got the version info, i closed SC. on the off chance i tried the modem, and now it works!
please note that before now when the modem isnt working i have tried dialing 2 or 3 times myself and that has never fixed anything.
so, i rebooted, and the modem still worked.
the only other clue at this point is that on the boots when the modem was working it was taking a LONG time, in the 1 to 5 minute range, it varied quite a lot, for the machine to shut down. however, on the boots when the modem was not working the machine shut down in just a few seconds.
in isolation i would be strongly tempted to blame this on some strange software config problem. however, given one clean format ago i couldnt send any email on a totally clean install of winXP this doesnt make any sense.
so, the hardware expert is now in posesion of this strange machine, and is going to start by testing the powersupply. he thinks this may be causing some of the problems if it is faulty. it looks like any further news will be a few days (at least) in arriving.
