HP t5550/t5565/t5570 Thin Clients - System BIOS

Restoring a Corrupt BIOS
If the BIOS on the thin client is corrupt, the BIOS must be restored before the thin client will boot to the operating system. To restore the BIOS, you will need the following:
- An external USB diskette drive or USB flash drive connected to the thin client
- HP Compaq Thin Client t5000 Series System BIOS Softpaq (for the product being restored) on diskette or USB flash drive
  note:
The BIOS recovery procedure works the same from USB floppy diskette or USB flash drive.
To restore a corrupted BIOS, complete the following instructions:
1. Place the latest BIOS image file on a USB flash drive or floppy diskette.
2. Rename the BIOS image file to 786R9.ROM for the restore process to work.
3. Insert the USB flash drive or floppy drive with diskette into a port on the corrupted system.
4. Power the system on and observe the USB device activity light flashes indicating the process has started.
The system will display a message showing the recovery process has started and when it has finished.
5. When the process is complete, the system reboots. Remove the USB device.
  note:
The process takes about 45 seconds using a flash drive or about 1.5 minutes using a floppy drive.
  warning:
Do not turn off power or attempt to reboot the thin client during the recovery process.
Updating a BIOS
To update the system BIOS, download the Softpaq (for the product being updated) from the HP Web site at: http://www.hp.com/, select Software and Driver Downloads, and then enter the model number of your thin client.
The Softpaq contains utilities for restoring or updating the system BIOS. Included in the Softpaq are several methods for changing or updating the BIOS version on your computer. The tools and appropriate BIOS images are contained in the following Softpaq directories:
  • DOS Flash – DOS utility that can be used locally or with a Preboot eXecution Environment (PXE) management application to update the system BIOS.
  • WFlash – Windows-based utility used to locally update the system BIOS on individual PCs through the Windows environment.
  • CEFlash – CE.net-based utility to locally update the system BIOS on individual PCs through the CE.net environment.
  • LFlash – Linux-based utility to locally update the system BIOS on individual PCs through the Linux environment.
To determine the BIOS family, version, and date on the thin client, press F10 during system power-on to run the F10 Setup utility, then select System Information.
To update the system BIOS, complete the following instructions:
  1. Download the Softpaq to a directory on your hard drive. The downloaded file is a self-extracting executable.
  2. From that drive and directory, execute the downloaded file and follow the on-screen instructions.
  3. Copy the appropriate utility to a diskette or USB flash drive to transfer to the thin client.
  warning:
Do not turn off power or attempt to reboot the computer during the upgrade process
For more information about your thin client, see the Troubleshooting Guide at http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c02634823/c02634823.pdf.
