| ============ Function 21, subfunction 13, subsubfunction 1 =========== |
| ======== Initialize + get information on the driver vmode.mdr. ======= |
| ====================================================================== |
| Parameters: |
| * eax = 21 - function number |
| * ebx = 13 - subfunction number |
| * ecx = 1 - number of the driver function |
| * edx = pointer to 512-bytes buffer |
| Returned value: |
| * if driver is not loaded |
| (never happens in the current implementation): |
| * eax = -1 |
| * ebx, ecx destroyed |
| * if driver is loaded: |
| * eax = 'MDAZ' (in fasm style, that is 'M' - low byte, 'Z' - high) |
| - signature |
| * ebx = current frequency of the scanning (in Hz) |
| * ecx destroyed |
| * buffer pointed to by edx is filled |
| Format of the buffer: |
| * +0: 32*byte: driver name, "Trans VideoDriver" |
| (without quotes, supplemented by spaces) |
| * +32 = +0x20: dword: driver version (version x.y is encoded as |
| y*65536+x), for the current implementation is 1 (1.0) |
| * +36 = +0x24: 7*dword: reserved (0 in the current implementation) |
| * +64 = +0x40: 32*word: list of supported videomodes (each word |
| is number of a videomode, after list itself there are zeroes) |
| * +128 = +0x80: 32*(5*word): list of supported frequences of the |
| scannings for videomodes: for each videomode listed in the |
| previous field up to 5 supported frequences are given |
| (unused positions contain zeroes) |
| Remarks: |
| * Function initializes the driver (if it is not initialized yet) |
| and must be called first, before others (otherwise they will do |
| nothing and return -1). |
| * The current implementation supports only one frequency |
| of the scanning on videomode. |

| * ecx = number of current videomode |
| Remarks: |
| * Driver must be initialized by call to |
| driver function 1. |
| * If only screen sizes are required, it is more expedient to use |
| function 14 taking into account that it |
| returns sizes on 1 less. |
