Technical Notes

Full name: Phoenix NoteBIOS 4.0 Hibernation Preparation Utility

PHDISK is a utility, for the Phoenix BIOS, that creates a file or hard disk partition large enough to hold the entire state of your computer so it can be safely powered down and later powered up, rather quickly, without losing the machine integrity state.

This Save-To-Disk feature is used for the Power Management and can be configured in the BIOS Setup program.

=======================================
Installation Notes:

The PHDISK utility of the notebook allows you to create a suspend-to-disk (STD) partition or file that is used to save the opened files when you activate STD mode and power off the computer. If you want to make use of the
STD feature, you need first to run the PHDISK utility. There are two options for executing this utility:
PHDISK /Create /Partition - you can choose to run Suspend-to-Disk and save your work into an allocated fixed disk partition. This option should be done before partitioning and formatting your hard disk. The advantage of this
option is that it is more secure since the files are saved in a separate partition and has no risk of being deleted. The disadvantage of this is that you need to allocate enough disk partition for future memory upgrade.
The STD partition should always be larger than the system memory RAM.
PHDISK /Create /File - you can also choose to run Suspend-to-Disk and save your work into a STD file. You do not need to allocate an extra disk partition when running this option. The advantage of this is that you do
not need to allocate or waste extra disk partition. The disadvantage of this option is that it is less secure since there is risk of deleting the STD file although the file is hidden.

If you select the PHDISK /Create /Partition, you need to do the following:
Before you run this option, you should carefully consider how much disk size you need to allocate for the STD partition. The STD partition should be larger than the installed system memory RAM. If you are planning to
install more memory in the future, it is recommended to allocate more disk space. Run FDISK under DOS and leave around 5% of disk space for Non-DOS partition. This will later be used by the PHDISK for creating the STD
partition. If you already run FDISK before, you need to delete the original
partition of the hard disk.
Load the notebook driver CD and look for the PHDISK program file. Run PHDISK /Create /Partition or PHDISK /C /P. The PHDISK utility program will automatically assign a disk size in reference to the installed system RAM
to be allocated for the STD partition. After PHDISK has completed the STD partition, you will be prompted to reboot the system and you can begin OS installation.

You may also use MS-DOS to partition a certain percentage of your hard disk and install first the OS you need. Afterwards, you can run PHDISK /C /P and it will create a STD partition based on the remaining unformatted disk
partition. Then, you may partition the remaining disk space as extended logical drive and format it.

If you select the PHDISK /Create /File, you need to do the following:
Creating a STD file is much simpler since you do not need to allocate an extra disk partition. Load the notebook driver CD and look for the PHDISK program file. Run PHDISK /Create /File or PHDISK /C /F. PHDISK will create
the SAVE2DSK.BIN file on Drive C. The size of this file will depend on the installed RAM memory of your computer. This file also is hidden and has read-only attributes. You must not delete this file.

Notes:
During power on or restart, the system will detect if STD partition or file is present. If not, it will show a red colored dialog box informing you that Save to Disk Partition Not Present and Save to Disk Feature Disabled.

Whenever you upgrade the memory, you need to delete the existing STD partition or file and create a new one according to the new memory size. Run PHDISK /Delete /Partition or PHDISK /Delete /File to delete existing
STD partition or file.

For more information on how to use the PHDISK utility, type PHDISK on the command prompt from the directory where the PHDISK command is located.

 

Thanks for sharing the info. I did a half-hearted search, but found way too much, and much of it unrelated to Windows. So, I was unsure which your question was related to.

Glad you found it.
