想請問關於燒錄機EEPROM跟Firmware之間的不同
最近在CD-R實驗室看到作者改LiteOn LDW-401S變LDW-411S,他先把LDW-401S的EEPROM備份下來,然後再更新Firmware成LDW-411S,最後又把EEPROM copy回去,我想請問一下,EEPROM不是electrically erasable programmable read-only memory嗎(這應該是硬體規格,所以原作者備份的是EEPROM中的程式??)??那請問燒錄機的EEPROM中紀錄的是關於燒錄機的什麼部分??另外Firmware不是用來控制燒錄機的程式嗎??那Firmware是紀錄在燒錄中哪一個硬體呢??
感謝各位 |
以 Lite-On 的 DVD-Recorder 為例,
EEPROM 中紀錄的是這台燒錄機的相關參數, 包括雷射頭功率校準, 區碼, 韌體資訊,等... FIRMWARE 是紀錄在另一顆 FLASHROM 上, 類似主機板的 BIOS 部分, 控制整個 RECORDER 的動作, 當需要相關參數的時候, 再從 EEPROM 中去讀取. 其實以 MEDIATEK 的晶片組為基礎的相關 DVD-ROM/RECORDER 都應是如此.. |

感謝,我大致了解了 |

有件事要請教大大(很抱歉因為無法寫信給您只好PO在這裏希望您能看到) 我有一台4KUS 1S40(=401S) 用 OminiPatcher 把官版軔体破解在執行弄成 1S81(=811S)，但是目前所有片子都不能讀且LED一直閃，我想改回去，但當初只backup了EEPROM 的 BIN 沒有 backup Flash，可以改回去嗎？要怎麼弄呢？ ps:當初是 follow 下面網址 upgrade 的 http://codeguys.rpc1.org/oc.html Method 1: OmniPatcher (universal method) Download an unscrambled stock (i.e., original) firmware for the drive that you are flashing to from either our firmware page or dhc014's firmware page. Download the OmniPatcher and read the documentation carefully. For the best compatibility, please make sure that you have version 2.2.0 or newer. Load the stock firmware with the OmniPatcher and apply the crossflashing patch (and while you're at it, any other patches that you want). When you are done, save it. Flash your drive with the OmniPatcher-patched firmware that you have just created. If your patched firmware is a flasher (i.e., with a .exe extension), simply double-click on the patched firmware and follow the instructions. If your patched firmware is a raw binary firmware (i.e., with a .bin extension), please use LtnFW to flash your drive. |
