Claim:
1. A method, comprising: training a differential data link, by a Basic Input/Output System (BIOS) of an Information Handling System (IHS), in a differential mode; training the differential data link, by the BIOS, in a first single-ended mode; training the differential data link, by the BIOS, in a second single-ended mode; operating the differential data link in the first single-ended mode with a first set of optimization parameters; monitoring, by the BIOS, a performance characteristic of the differential data link in the first single-ended mode; after operating the differential data link in the first single-ended mode and in response to a determination by the BIOS that the performance characteristic of the differential data link in the first single-ended mode is below a threshold, operating the differential data link in the second single-ended mode with a second set of optimization parameters; monitoring, by the BIOS, the performance characteristic of the differential data link in the second single-ended mode; and after operating the differential data link in the second single-ended mode and in response to a determination by the BIOS that the performance characteristic of the differential data link in the second single-ended mode is below the threshold, operating the differential data link in the differential mode with a third set of optimization parameters.
