ASUS Ascent GX10 — USB 開機重灌指南

 NVIDIA DGX OS 7.4.0-3 安裝流程

前置準備

• USB 隨身碟：至少 16 GB
• 有線 USB 鍵盤：直接插 GX10 後方 USB 孔（開機階段禁用藍牙/無線接收器）
• DGX OS ISO：從 ASUS 官方下載頁 (https://www.asus.com/hk/networking-iot-servers/desktop-ai-supercomputer/ultra-small-ai-supercomputers/asus-ascent-gx10/helpdesk_download?model2Name=ASUS-Ascent-GX10) 下載 NVIDIA DGX OS for ASUS Ascent GX10 7.4.0-3（約 9.27 GB）
• SHA-256 校驗：E9A8AF7379F258A5781EC5E735A30784DFCB2913FE6417DBFC8E438A86CBEB5D

 

Step 1：製作可開機 USB

標準的直接複製檔案或基本 Rufus 設定，往往會破壞 NVIDIA DGX Spark 架構所需的 EFI 分區配置。請嚴格按照以下設定操作：

1. 打開 Rufus（Windows）
2. 裝置：選擇目標 USB 隨身碟
3. 開機選項：點「選取」→ 載入 DGX OS .iso 檔案
4. 關鍵設定：
• 分割配置類型：GPT
• 目標系統：UEFI（非 CS M）
• 檔案系統：FAT32
5. 點擊 開始 → ISO 映像模式寫入（非 DD 模式）

 

Step 2：清除並調整 UEFI/BIOS 設定

GX10 會在系統金鑰或 Secure Boot 配置處於無效狀態時，封鎖恢復媒體。必須重置這些設定：

2a. 重置 UEFI 預設值

1. 開機 → 反覆按 [Del] 進入 BIOS
2. 導航至 Save & Exit 頁籤
3. 選擇 Restore Defaults（Load Optimized Defaults）→ 確認

2b. 修復 Secure Boot 金鑰

1. 進入 Security → Secure Boot
2. 將 Secure Boot 改為 Custom
3. 選擇 Restore Factory Keys → 確認
4. 將 Secure Boot 改回 Enabled / Standard
5. 按 [F4] 儲存變更並重啟

 

Step 3：使用 Boot Override 啟動安裝程式

GX10 預設優先載入內部 NVMe 儲存，如果先前發生過開機錯誤，標準的開機優先順序設定會被忽略。必須使用 Boot Override：

1. 保持 USB 已插入 → 重啟時反覆按 [Del] 進入 BIOS
2. 直接導航至 Save & Exit 頁籤
3. 向下捲動至 Boot Override 區塊
4. 選擇標示為 UEFI: USB... Partition 1 的項目 → 按 Enter
5. GRUB 選單載入後：
• 選 DGX Spark Installation Options
• 選 Install DGX OS 7.4.0 for DGX Spark
6. 等待安裝完成
