Dimension 8250 Bios A04 Com Ports

​ I have tried unsuccessfully to install the software for my Sony Ericsson V800 mobile (cell) phone and now I'm trying to undo the failed installs. This involves deleting the Com Ports that were assigned during the previous installations. ​

​ ​

​ I noted that Com 5 and Com 6 were created during these failed installations and tried to deleted them in Bios at system start up. However, I couldn't find these Com Ports listed under integrated devices. I know that these ports are being used because under the Advanced properties panel in Phone & Modem settings it says they are used. ​

​ ​

​ I don't even know if Com 5 & 6 should be deleted but as I'm not getting the V800 software to work, I thought I delete whatever system changes I'd made. ​

​ ​

​ Any ideas anyone, please? ​

​ ​

​ Thank you. ​
