You are selecting the correct option in the list in the attachment.
Wired network connectivity is built into the base tinycore install, which in my case allows me to connect from inside the vm and download any extension I wish (including open-vm-tools).
Did you have the ide and scsi disks configured in your vm setup previously (you should have seen at least one of them in the tc-install installation target options)?
i corrected the disk detection issue & now disk is detected as sda1
so i opened up "App browser" and using following steps shown in screenshots, i started to download "open-VM-tools"
it took some times and system were showing all downloads completed successfully
but unfortunately at the end, in App browser status, system shows "failed"
screenshots of all steps, here you are
please tell me if i am correct in all steps
