19 // Details: |
|
20 // - Load a Physical Device Driver for the RAM Media Driver. |
|
21 // - Find the internal drive: type == EMediaRam |
|
22 // - Display and adjust various drive capabilities, verify results |
|
23 // are as expected. |
|
24 // - Read and write the drive using various drive sizes, verify results |
|
25 // are as expected. |
|
26 // - Format the drive, verify results. |
|
27 // - Set original size and reformat. |
|
28 // Platforms/Drives/Compatibility: |
