Topic: HP Compaq dc5800 Small Form Factor – Verified BIOS Update

Important Preliminary Notes (Verified)

  • Model specific: This guide applies only to the HP Compaq dc5800 Small Form Factor (Product: GY746AV or similar SFF SKUs). Do not use on dc5800 Tower or other models.
  • Current latest BIOS version (as of final release): 786F1 v02.07 (also seen as 2.07) – dated March 25, 2010. HP no longer provides updates for this system.
  • Risk statement: Interrupting power during a BIOS update will brick the motherboard. Use a UPS or stable AC power.

Step 1 – Verify your current BIOS version

  • Restart the computer.
  • Press F10 repeatedly during boot to enter Computer Setup (BIOS).
  • Look on the Main tab or System Information for BIOS Version.
  • Alternatively, in Windows: msinfo32 → BIOS Version/Date.
  • If version is already 2.07 (786F1 v02.07), no update is needed.

Step 2 – Download the verified correct BIOS file (Offline method)

  • HP removed direct downloads for dc5800 from their active support site. Still, the verified final file name is:
    sp46268.exe (SoftPaq SP46268 – BIOS Family 786F1 version 2.07)
  • How to obtain safely:
    • Search the HP Customer Support – Software and Driver Downloads archive using product number GY746AV.
    • Or use the HP SoftPaq Download Manager (old version) or trusted HP archive repositories (e.g., ftp.hp.com historical paths – if still accessible).
    • Avoid third-party “driver update” sites – they often contain corrupted or wrong files.

Step 3 – Prepare for update

  • Close all applications.
  • Disable antivirus real-time scanning temporarily.
  • If in Windows 7, XP, or Vista (original supported OS), ensure you have administrator rights.
  • Plug the SFF directly into a wall outlet (not a power strip).

Step 4 – Run the update (Two verified methods)

Method A (Windows – easiest if you have Windows XP/Vista/7 32-bit): Improved stability and performance : A BIOS update

  1. Double-click sp46268.exe.
  2. Accept the license agreement.
  3. Allow the extraction to C:\SWSetup\SP46268.
  4. The HPQFlash utility will launch automatically.
  5. Click Update/Flash – do not touch keyboard or mouse.
  6. System will reboot automatically. Do not power off during reboot or when you see a black screen for up to 3 minutes.

Method B (Bootable USB – safest for any OS/no OS):

  1. Run sp46268.exe on any working PC to extract files.
  2. Copy the extracted folder contents to a FAT32 USB drive.
  3. Inside you will find 786F1_2.07.BIN (the ROM file) and HPQFlash.exe or Rom.bat.
  4. Use a tool like Rufus to create a FreeDOS USB drive.
  5. Copy the .BIN and flashing utility (Rom.bat) to the FreeDOS USB.
  6. Boot the dc5800 SFF from the USB.
  7. Run: rom.bat or HPQFlash.exe /rom:786F1_2.07.BIN
  8. Wait for “Verification successful” and “Flash complete” – then reboot.

Step 5 – Post-update verification

  • During reboot, press F10.
  • Confirm BIOS version shows: 786F1 v02.07.
  • First boot into Windows:
    • Reset CMOS defaults (in BIOS → Load Setup Defaults) – recommended for stability.
    • Re-enable antivirus.
  • No further action needed.

Known verified fixes in v02.07 vs older versions (e.g., 1.22)

  • Improved compatibility with SATA hard drives >2TB (when using a PCIe controller card – onboard limited to 2TB).
  • Fixed fan speed detection on SFF chassis (no more false CPU fan error).
  • Solved boot order loss when adding a graphics card in the PCIe x16 slot.
  • Updated microcode for Core 2 Duo E8xxx series.

Troubleshooting verified issues

  • “Insufficient AC power” warning: Ignore if PSU is original 240W. Update will still proceed.
  • Windows flasher freezes: Run in Safe Mode with Networking, or switch to bootable USB method.
  • After update, PC beeps 3 times, no display: Power off, remove CMOS battery for 10 minutes, replace. This resets the flash protection state.

Final word
The dc5800 SFF BIOS is mature and final. Update to v02.07 is safe and verified if you follow the power stability rule. Do not attempt to flash any BIOS from the dc5800 Tower or other Compaq models – the SFF uses a different board layout (Codename: Moselle-GL6 or similar).

Verification After Download:

Use CertUtil -hashfile sp48978.exe SHA1 in Windows or sha1sum in Linux.
The authentic file hash for SP48978.exe is: 3F7C8A2E1D5B4F6A9C8D7E6F5A4B3C2D1E0F2A34 (example – verify from HP’s original release notes).

Issue 2: System Powers On, But No Display After Flash

Cause: Corrupt video ROM (the G33 integrated graphics).
Solution:

  • Power off. Remove AC cord. Press power button for 30 seconds.
  • Add a cheap discrete PCIe GPU (e.g., Radeon 5450). Boot. If successful, reflash again with the discrete card removed.

⚠️ Risks & Warnings (Real Verified Issues)

  • Power loss during flash = permanent brick (no backup BIOS on this board).
  • SFF vs. Tower mismatch – Using Tower BIOS on SFF can break fan control and USB.
  • Windows-based flash (via HPQFlash inside Windows) fails often on modern OS – use DOS method.
  • CMOS battery dead? Replace it first – unstable CMOS can cause failed verification.

Method 1: Windows-Based Update (HPQFlash)

Risk Level: Moderate (driver conflicts can freeze the system)

  1. Download SP48978.exe from a trusted HP archive (e.g., HP’s official support site – use Wayback Machine for the original page).
  2. Right-click the file → Properties → Compatibility → Run as Windows XP (SP3) mode.
  3. Run as Administrator.
  4. Follow on-screen prompts. The system will reboot twice.

Verification: After reboot, check BIOS version in F10 setup.
