OPNsense on the Lenovo V530s (Machine Type 11B) with the Intel i210-T1 NIC

以下是 Lenovo V530s(Machine Type 11B)安裝 Intel i210-T1 並運行 OPNsense 的配置要點,請照此佈線與設定介面。

Here is the setup guide for running OPNsense on the Lenovo V530s (Machine Type 11B) with the Intel i210-T1 NIC. Please follow the cabling and interface assignment below.

1. 硬體前置作業 / Hardware Prerequisite

  • Intel i210-T1 必須更換為 Low-Profile(矮擋板)Bracket。
    The V530s uses a low-profile PCIe slot, so the i210-T1 (which ships with a full-height bracket) must be swapped to a low-profile bracket before installation, otherwise it will not fit the chassis.
  • 主機板內建網路埠:Realtek RTL8111(建議作為 LAN 局域網 端)。
    Onboard port: Realtek RTL8111 (recommended as the LAN side).
  • Intel i210-T1 網路埠:穩定度極高,強烈建議作為 WAN 網際網路 端,直接連線至你的數據機 / Modem。
    Intel i210-T1: extremely stable, strongly recommended as the WAN side, connected directly to your modem.

2. OPNsense 介面對應 / Interface Mapping

OPNsense 設備名
實體網卡
建議角色
連接對象
igb0
Intel i210-T1
WAN
Modem / 數據機
re0
Realtek RTL8111 (onboard)
LAN
內部交換機 / 設備

3. 安裝與指派步驟 / Setup Steps

  1. 關機斷電,將 i210-T1(已裝矮擋板)插入 V530s 的 PCIe 槽。
    Power off, install the i210-T1 (with low-profile bracket) into the PCIe slot.
  2. 佈線:Modem → i210-T1 埠(WAN);內網交換機/PC → 主機板 RJ45(LAN)。
    Cabling: Modem → i210-T1 port (WAN); LAN switch/PC → onboard RJ45 (LAN).
  3. 開機進 OPNsense 初始設定,依提示指派介面:
    On first boot, when prompted to assign interfaces:
    • 輸入 igb0 作為 WAN
    • 輸入 re0 作為 LAN
  4. 若 re0(Realtek)出現斷流/不穩,建議在 OPNsense 安裝官方 Realtek 驅動插件 os-realtek-re,提升 RTL8111 穩定度。
    If re0 is unstable, install the os-realtek-re plugin for better RTL8111 support.

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

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
