The value `8` is copied to `%cl` in preparation for a new string operation (like our previous `movsw`). Now, `stosw` is executed 8 times. This instruction copies a `0` value to the address pointed to by the destination register (`%di`, which is `0x800`), and increments it. This is repeated another 7 times, so `%di` ends up with value `0x810`. Effectively, this clears the address range `0x800`-`0x80f`. This range is used as a (fake) partition table for writing the MBR back to disk.Finally, the sector field for the CHS addressing of this fake partition is given the value 1 and a jump is made to the main function from the relocated code.

The BIOS has a predefined set of services, requested by applications as software-generated interrupts through the `int` instruction and receiving arguments in registers (in this case, `%ah`). Here, particularly, we are requesting the number of clock ticks since last midnight; this value is computed by the BIOS through the RTC (Real Time Clock). This clock can be programmed to work at frequencies ranging from 2 Hz to 8192 Hz. The BIOS sets it to 18.2 Hz at startup. When the request is satisfied, a 32-bit result is returned by the BIOS in registers `%cx` and `%dx` (lower bytes in `%dx`). This result (the `%dx` part) is copied to register `%di`, and the value of the `TICKS` variable is added to `%di`. This variable resides in [.filename]#boot0# at offset `_TICKS` (a negative value) from register `%bp` (which, recall, points to `0x800`). The default value of this variable is `0xb6` (182 in decimal). Now, the idea is that [.filename]#boot0# constantly requests the time from the BIOS, and when the value returned in register `%dx` is greater than the value stored in `%di`, the time is up and the default selection will be made. Since the RTC ticks 18.2 times per second, this condition will be met after 10 seconds (this default behavior can be changed in the [.filename]#Makefile#). Until this time has passed, [.filename]#boot0# continually asks the BIOS for any user input; this is done through `int 0x16`, argument `1` in `%ah`." ], "previous_source": "", "target": [ "" ], "id_hash": 8510496506339344780, "content_hash": 8510496506339344780, "location": "documentation/content/en/books/arch-handbook/boot/_index.adoc:446", "context": "", "note": "type: Plain text", "flags": "", "labels": [], "state": 0, "fuzzy": false, "translated": false, "approved": false, "position": 76, "has_suggestion": false, "has_comment": false, "has_failing_check": false, "num_words": 253, "source_unit": "https://translate-dev.freebsd.org/api/units/1436453/?format=api", "priority": 100, "id": 1497581, "web_url": "https://translate-dev.freebsd.org/translate/documentation/booksarch-handbookboot_index/ko/?checksum=f61b5b7b628f418c", "url": "https://translate-dev.freebsd.org/api/units/1497581/?format=api", "explanation": "", "extra_flags": "", "pending": false, "timestamp": "2023-03-07T02:51:51.475352Z" }, { "translation": "https://translate-dev.freebsd.org/api/translations/documentation/booksarch-handbookboot_index/ko/?format=api", "source": [ "Whether a key was pressed or the time expired, subsequent code validates the selection.
