Hey there,

My boss is in Londona nd I'm in NY and we're trying to build a couple of machiens with our ghost image from NY.  The link is fast and 4 machines built no problem.  The last two were puirchased without proper specs given and are using a different NIC.  The problem is is that the cards in these two machine are onboard 3Com 3C920 intergrated NICs.  Trying to get this card to boot on the netwoprk has been troubleing and the Cisco switch is all weird.  The solution we had for the other machines was to set the cards to boot 100/Full Duplex, which worked.  However, we can't seeem to come up with the right parameters for this other card type.

Ideas on how to force the card to be 100 Full Duplex when starting with a Ghost Boot disk?

Any help would be GREATLY appreciated.

Thanks.

Howard

hi, what is the way you preferred for changing the default work mode from auto to full-duplex? by changing the default configuration file (text file)? how did you finish for the other two cards?

btw, if you can not do it at NIC sides, why dont you try changing the port modes of your cisco switch?

bbao,

The default configuration file is how I need to do this, as it is a ghost boot disk, booting into PC DOS.  As far as changing the settings on the cisco switch, as of writing the request, there was no one in the London office (as it was an early weekend for them) and we didn't have the docs for their cisco switch.

So what I need to do is make the changes on the config file when the unit boots.  I 've been told by 3Com that the settings can be changed on the imbedded NIC and those changes will stick, but it reuqires the config.exe file from 3Com.  We used that, but the program craps out and the changes never take.

So, what I want to try and do is have it set on boot up, IF its possible.

Thanks.

yep, that's the one.  As I said,  when run from a boot disk PC DOS session, the program craps out.  When run from a command window booting into windows XP, it gives memory error messages and forces the CMD window to close.

the DOS program crashes on all computers you tested or only one of them?

hi, sorry for late reply. the setup utility 3C90XCFG.EXE is designed for DOS, so the right way to change the imbedded settings of NICs is to boot under DOS, run 3C90XCFG.EXE, then boot to other OS.
