Older cards won't autodetect. They just beacon your ring if set incorrectly. All IBM shared-RAM adapters and compatibles will tell you the ring speed on either open or init (I can't remember offhand) so a default isn't used in these cases (these are set by dip switch or configuration program anyway.) Autodetecting adapters fail on open with a particular error code if inserting at the wrong speed, so you can reset the speed and retry the open. In these cases the default is the last speed it successfully opened at, stored in nonvolatile storage on the adapter. So I guess my question is what is the purpose of having a default hard-coded someplace in the kernel?
