2565 | * In the first two cases it is also possible to use FIRST |

2566 | instead of 1, SECOND instead of 2, but it is not recommended |
- | |
2567 | for convenience of transition to the future extensions. |
- | |
2568 | * Limitation n<=39 is imposed. |
- | |
2569 | * Names of folders and file dir1,...,dirn,file must have the |
- | |
2570 | format 8.3: name no more than 8 characters, dot, extension no |
- | |
2571 | more than 3 characters. Trailing spaces are ignored, no other |
- | |
2572 | spaces is allowed. If name occupies equally 8 characters, |
- | |
2573 | dot may be omitted (though it is not recommended to use this |
- | |
2574 | feature for convenience of transition to the future extensions). |
- | |
2575 | * This function does not support folders on ramdisk. |

2587 | =========== Function 58, subfunction 0 - read file/folder. =========== |
- | |
2588 | ====================================================================== |
- | |
2589 | Parameters: |
- | |
2590 | * eax = 58 |
- | |
2591 | * ebx = pointer to the information structure |
- | |
2592 | Format of the information structure: |
- | |
2593 | * +0: dword: 0 = subfunction number |
- | |
2594 | * +4: dword: first block to read (beginning from 0) |
- | |
2595 | * +8: dword: amount of blocks to read |
- | |
2596 | * +12 = +0xC: dword: pointer to buffer for data |
- | |
2597 | * +16 = +0x10: dword: pointer to buffer for system operations |
- | |
2598 | (4096 bytes) |
- | |
2599 | * +20 = +0x14: ASCIIZ-name of file, the rules of names forming are |
- | |
2600 | given in the general description |
- | |
2601 | Returned value: |
- | |
2602 | * eax = 0 - success, otherwise file system error code |
- | |
2603 | * ebx = file size (in bytes) or -1=0xffffffff, if file was not found |
- | |
2604 | Remarks: |
- | |
2605 | * Block size is 512 bytes. |
- | |
2606 | * This function is obsolete, for reading files use subfunction 0 |
- | |
2607 | of function 70, for reading folders - subfunction 1 of |
- | |
2608 | function 70. |
- | |
2609 | * Function can read contents of a folder. Only FAT file system is |
- | |
2610 | supported. The format of FAT-folder is described |
- | |
2611 | in any FAT documentation. |
- | |
2612 | * Size of a folder is determined by size of FAT clusters chain. |
- | |
2613 | * If file was ended before last requested block was read, |
- | |
2614 | the function will read as many as it can, and after that return |
- | |
2615 | eax=6 (EOF). |
- | |
2616 | * Function can read root folders /rd/1,/fd/x,/hd[n]/x, but |
- | |
2617 | in the first two cases the current implementation does not follow |
- | |
2618 | to the declared rules: |
- | |
2619 | for /rd/1: |
- | |
2620 | * if one want to read 0 blocks, function considers, |
- | |
2621 | that he requested 1; |
- | |
2622 | * if one requests more than 14 blocks or starting block is |
- | |
2623 | not less than 14, function returns eax=5 (not found) and ebx=-1; |
- | |
2624 | * size of ramdisk root folder is 14 blocks, |
- | |
2625 | 0x1C00=7168 bytes; but function returns ebx=0 |
- | |
2626 | (except of the case of previous item); |
- | |
2627 | * strangely enough, it is possible to read 14th block (which |
- | |
2628 | generally contains a garbage - I remind, the indexing begins |
- | |
2629 | from 0); |
- | |
2630 | * if some block with the number not less than 14 was requested, |
- | |
2631 | function returns eax=6(EOF); otherwise eax=0. |
- | |
2632 | For /fd/x: |
- | |
2633 | * if the start block is not less than 14, function returns |
- | |
2634 | eax=5 (not found) and ebx=0; |
- | |
2635 | * note that format of FAT12 allows floppies with the root size |
- | |
2636 | more or less than 14 blocks; |
- | |
2637 | * check for length is not performed; |
- | |
2638 | * if data was successful read, function returns |
- | |
2639 | eax=0,ebx=0; otherwise eax=10 (access denied), ebx=-1. |
- | |
2640 | * The function handles reading of special folders /,/rd,/fd,/hd[n]; |
- | |
2641 | but the result does not correspond to expected (on operations with |
- | |
2642 | normal files/folders), does not follow the declared rules, |
- | |
2643 | may be changed in future versions of the kernel and consequently |
- | |
2644 | is not described. To obtain the information about the equipment |
- | |
2645 | use subfunction 11 of function 18 or |
- | |
2646 | read corresponding folder with subfunction 1 of function 70. |

- | |
2651 | Parameters: |
- | |
2652 | * eax = 58 - function number |
- | |
2653 | * ebx = pointer to the information structure |
- | |
2654 | Format of the information structure: |
- | |
2655 | * +0: dword: 8 = subfunction number |
- | |
2656 | * +4: dword: number of block to read (beginning from 0) |
- | |
2657 | * +8: dword: ignored (set to 1) |
- | |
2658 | * +12 = +0xC: dword: pointer to buffer for data (512 bytes) |
- | |
2659 | * +16 = +0x10: dword: pointer to buffer for system operations |
- | |
2660 | (4096 bytes) |
- | |
2661 | * +20 = +0x14: ASCIIZ-name of device: case-insensitive, one of |
- | |
2662 | /rd/1 = /RamDisk/1, /hd/n = /HardDisk/n, |
- | |
2663 | 1<=n<=4 - number of device: 1=IDE0, ..., 4=IDE3. |
- | |
2664 | Instead of digits it is allowed, though not recommended for |
- | |
2665 | convenience of transition to future extensions, to use |
- | |
2666 | 'first','second','third','fourth'. |
- | |
2667 | Returned value: |
- | |
2668 | * for device name /hd/xxx, where xxx is not in the list above: |
- | |
2669 | * eax = ebx = 1 |
- | |
2670 | * for invalid device name (except for the previous case): |
- | |
2671 | * eax = 5 |
- | |
2672 | * ebx does not change |
- | |
2673 | * if LBA-access is disabled by subfunction 11 of function 21: |
- | |
2674 | * eax = 2 |
- | |
2675 | * ebx destroyed |
- | |
2676 | * for ramdisk: attempt to read block outside ramdisk |
- | |
2677 | (18*2*80 blocks) results in |
- | |
2678 | * eax = 3 |
- | |
2679 | * ebx = 0 |
- | |
2680 | * for successful read: |
- | |
2681 | * eax = ebx = 0 |
- | |
2682 | Remarks: |
- | |
2683 | * Block size is 512 bytes; function reads one block. |
- | |
2684 | * Do not depend on returned value, it can be changed |
- | |
2685 | in future versions. |
- | |
2686 | * Function requires that LBA-access to devices is enabled by |
- | |
2687 | subfunction 11 of function 21. To check this one can use |
- | |
2688 | subfunction 11 of function 26. |
- | |
2689 | * LBA-read of floppy is not supported. |
- | |
2690 | * Function reads data on physical hard drive; if for any reason |
- | |
2691 | data of the concrete partition are required, application must |
- | |
2692 | define starting sector of this partition (either directly |
- | |
2693 | through MBR, or from the full structure returned by |
- | |
2694 | subfunction 11 of function 18). |
- | |
2695 | * Function does not check error code of hard disk, so request of |
- | |
2696 | nonexisting sector reads something (most probably it will be |
- | |
2697 | zeroes, but this is defined by device) and this is considered |
- | |
2698 | as success (eax=0). |

2704 | * eax = 58 - function number |

2712 | * +20 = +0x14: (only second character is checked) |

2713 | /rd=/RAMDISK or /hd=/HARDDISK |
- | |
2714 | Returned value: |
- | |
2715 | * if the second character does not belong to set {'r','R','h','H'}: |
- | |
2716 | * eax = 3 |
- | |
2717 | * ebx = ecx = dword [fileinfo] = 0 |
- | |
2718 | * for ramdisk: |
- | |
2719 | * eax = 0 (success) |
- | |
2720 | * ebx = total number of clusters = 2847 |
- | |
2721 | * ecx = number of free clusters |
- | |
2722 | * dword [fileinfo] = cluster size = 512 |
- | |
2723 | * for hard disk: base and partition are defined by subfunctions |
- | |
2724 | 7 and 8 of function 21: |
- | |
2725 | * eax = 0 (success) |
- | |
2726 | * ebx = total number of clusters |
- | |
2727 | * ecx = number of free clusters |
- | |
2728 | * dword [fileinfo] = cluster size (in bytes) |
- | |
2729 | Remarks: |
- | |
2730 | * Be not surprised to strange layout of 4th returned parameter |
- | |
2731 | - when this code was writing, at system calls application got |
- | |
2732 | only registers eax,ebx,ecx (from pushad-structure transmitted |
- | |
2733 | as argument to the system function). Now it is corrected, so, |
- | |
2734 | probably, it is meaningful to return cluster size in edx, while |
- | |
2735 | this function is not used yet. |
- | |
2736 | * There exists also subfunction 11 of function 18, |
- | |
2737 | which returns information on file system. From the full table |
- | |
2738 | of disk subsystem it is possible to deduce cluster size (there |

2739 | it is stored in sectors) and total number of clusters |
