Appendix C Installing and Using TFTP Starting an HP Server from a remote boot image requires that you have already created an alternate bootable floppy image file and that this image is available in the base directory used by the TFTP server. After the HP Server Remote Management Card processes a remote reboot, the feature is disabled automatically so that the next boot will be a local boot. You use the HP Copydisk utility to create a floppy image file. The 1.44MB file created contains a sector-by-sector copy of the floppy plus a 32-byte Copydisk header; you can also use generic floppy image files (no header) created with other utilities. The image file (usually with the extension .DSK), when accessed via TFTP, is interpreted by the HP Server with the HP Server Remote Management Card as if it were a local floppy disk image. Thus, the HP Server boots using this image as if it were accessing a bootable disk stored in floppy drive A. The ability to create a floppy boot image opens up powerful remote administration possibilities. A system administrator can create boot floppy images to: • update the server BIOS • change and/or update software drivers • boot your various diagnostic utilities • boot virus-checking software NOTE Check the HP Server's BIOS Setup program (typically, accessed by pressing F2 when prompted during the boot process) to ensure that the floppy drive is positioned at the top of the list of bootable devices in the boot order. Creating a Floppy Boot Image Before you can create a boot image, you must get a copy of the HP utility "copydisk.exe". NOTE Do not confuse HP's copydisk.exe with the DOS utility diskcopy.exe supplied with Microsoft MS-DOS operating systems. Copydisk can be found on the HP Netserver Navigator CD in the directory \ttrc\us 79

Appendix C
Installing and Using TFTP
Starting an HP Server from a remote boot image requires that you have already
created an alternate bootable floppy image file and that this image is available in
the base directory used by the TFTP server. After the HP Server Remote
Management Card processes a remote reboot, the feature is disabled automatically
so that the next boot will be a local boot.
You use the HP Copydisk utility to create a floppy image file. The 1.44MB file
created contains a sector-by-sector copy of the floppy plus a 32-byte Copydisk
header; you can also use generic floppy image files (no header) created with other
utilities. The image file (usually with the extension .DSK), when accessed via
TFTP, is interpreted by the HP Server with the HP Server Remote Management
Card as if it were a local floppy disk image. Thus, the HP Server boots using this
image as if it were accessing a bootable disk stored in floppy drive A.
The ability to create a floppy boot image opens up powerful remote
administration possibilities.
A system administrator can create boot floppy
images to:
•
update the server BIOS
•
change and/or update software drivers
•
boot your various diagnostic utilities
•
boot virus-checking software
NOTE
Check the HP Server's BIOS Setup program (typically,
accessed by pressing F2 when prompted during the boot
process) to ensure that the floppy drive is positioned at the top
of the list of bootable devices in the boot order.
Creating a Floppy Boot Image
Before you can create a boot image, you must get a copy of the HP utility
"copydisk.exe".
NOTE
Do not confuse HP's
copydisk.exe
with the DOS utility
diskcopy.exe
supplied with Microsoft MS-DOS operating
systems.
Copydisk can be found on the
HP Netserver Navigator CD
in the directory
\ttrc\us
