|
|
|
+ * Constructor for emulator instances.
|
|
|
+ *
|
|
|
+ * Usage: `var emulator = new V86(options);`
|
|
|
+ *
|
|
|
+ * Options can have the following properties (all optional, default in parenthesis):
|
|
|
+ *
|
|
|
+ * - `memory_size number` (16 * 1024 * 1024) - The memory size in bytes, should
|
|
|
+ * be a power of 2.
|
|
|
+ * - `vga_memory_size number` (8 * 1024 * 1024) - VGA memory size in bytes.
|
|
|
+ *
|
|
|
+ * - `autostart boolean` (false) - If emulation should be started when emulator
|
|
|
+ * is ready.
|
|
|
+ *
|
|
|
+ * - `disable_keyboard boolean` (false) - If the keyboard should be disabled.
|
|
|
+ * - `disable_mouse boolean` (false) - If the mouse should be disabled.
|
|
|
+ *
|
|
|
+ * - `network_relay_url string` (No network card) - The url of a server running
|
|
|
+ * websockproxy. See [networking.md](networking.md). Setting this will
|
|
|
+ * enable an emulated network card.
|
|
|
+ *
|
|
|
+ * - `bios Object` (No bios) - Either a url pointing to a bios or an
|
|
|
+ * ArrayBuffer, see below.
|
|
|
+ * - `vga_bios Object` (No VGA bios) - VGA bios, see below.
|
|
|
+ * - `hda Object` (No hard disk) - First hard disk, see below.
|
|
|
+ * - `fda Object` (No floppy disk) - First floppy disk, see below.
|
|
|
+ * - `cdrom Object` (No CD) - See below.
|
|
|
+ *
|
|
|
+ * - `bzimage Object` - A Linux kernel image to boot (only bzimage format), see below.
|
|
|
+ * - `initrd Object` - A Linux ramdisk image, see below.
|
|
|
+ * - `bzimage_initrd_from_filesystem boolean` - Automatically fetch bzimage and
|
|
|
+ * initrd from the specified `filesystem`.
|
|
|
+ *
|
|
|
+ * - `initial_state Object` (Normal boot) - An initial state to load, see
|
|
|
+ * [`restore_state`](#restore_statearraybuffer-state) and below.
|
|
|
+ *
|
|
|
+ * - `filesystem Object` (No 9p filesystem) - A 9p filesystem, see
|
|
|
+ * [filesystem.md](filesystem.md).
|
|
|
+ *
|
|
|
+ * - `serial_container HTMLTextAreaElement` (No serial terminal) - A textarea
|
|
|
+ * that will receive and send data to the emulated serial terminal.
|
|
|
+ * Alternatively the serial terminal can also be accessed programatically,
|
|
|
+ * see [serial.html](../examples/serial.html).
|
|
|
+ *
|
|
|
+ * - `screen_container HTMLElement` (No screen) - An HTMLElement. This should
|
|
|
+ * have a certain structure, see [basic.html](../examples/basic.html).
|
|
|
+ *
|
|
|
+ * ***
|
|
|
+ *
|
|
|
+ * There are two ways to load images (`bios`, `vga_bios`, `cdrom`, `hda`, ...):
|
|
|
+ *
|
|
|
+ * - Pass an object that has a url. Optionally, `async: true` and `size:
|
|
|
+ * size_in_bytes` can be added to the object, so that sectors of the image
|
|
|
+ * are loaded on demand instead of being loaded before boot (slower, but
|
|
|
+ * strongly recommended for big files). In that case, the `Range: bytes=...`
|
|
|
+ * header must be supported on the server.
|
|
|
+ *
|
|
|
+ * ```javascript
|
|
|
+ * // download file before boot
|
|
|
+ * bios: {
|
|
|
+ * url: "bios/seabios.bin"
|
|
|
+ * }
|
|
|
+ * // download file sectors as requested, size is required
|
|
|
+ * hda: {
|
|
|
+ * url: "disk/linux.iso",
|
|
|
+ * async: true,
|
|
|
+ * size: 16 * 1024 * 1024
|
|
|
+ * }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * - Pass an `ArrayBuffer` or `File` object as `buffer` property.
|
|
|
+ *
|
|
|
+ * ```javascript
|
|
|
+ * // use <input type=file>
|
|
|
+ * bios: {
|
|
|
+ * buffer: document.all.hd_image.files[0]
|
|
|
+ * }
|
|
|
+ * // start with empty hard disk
|
|
|
+ * hda: {
|
|
|
+ * buffer: new ArrayBuffer(16 * 1024 * 1024)
|
|
|
+ * }
|
|
|
+ * ```
