| * DOSVM_Int11Handler (WINEDOS16.117) |
| * |
| * Handler for int 11h (get equipment list). |
| * |
| * |
| * Borrowed from Ralph Brown's interrupt lists: |
| * |
| * bits 15-14: number of parallel devices |
| * bit 13: [Conv] Internal modem |
| * bit 12: reserved |
| * bits 11- 9: number of serial devices |
| * bit 8: reserved |
| * bits 7- 6: number of diskette drives minus one |
| * bits 5- 4: Initial video mode: |
| * 00b = EGA,VGA,PGA |
| * 01b = 40 x 25 color |
| * 10b = 80 x 25 color |
| * 11b = 80 x 25 mono |
| * bit 3: reserved |
| * bit 2: [PS] =1 if pointing device |
| * [non-PS] reserved |
| * bit 1: =1 if math co-processor |
| * bit 0: =1 if diskette available for boot |
| * |
| * |
| * Currently the only of these bits correctly set are: |
| * |
| * bits 15-14 } Added by William Owen Smith, |
| * bits 11-9 } wos@dcs.warwick.ac.uk |
| * bits 7-6 |
| * bit 2 (always set) ( bit 2 = 4 ) |
| * bit 1 } Robert 'Admiral' Coeyman |
| * All *nix systems either have a math processor or |
| * emulate one. |
