You can connect a PATA hard drive. However, HP does not recommend its use .
System Setup and Boot
Basic system information regarding file, storage, security, and power configuration is main-
tained in the Setup Utility held in the system ROM. The Setup Utility is accessed by pressing the
F10
key as soon as the computer is turned on. If the screen prompt opportunity is missed, a
restart will be necessary.
Failsafe Boot Block ROM
The computer comes with a reprogrammable flash system ROM (read only memory).
NOTE
: No USB device of any type will function during bootblock recovery.
To upgrade the ROM, you may:
a. Order an upgraded ROMPaq diskette from HP.
or
b. Download the latest ROMPaq images from the HP Web site (www.hp.com).
All ROM images used with HPQFlash and SSM are digitally signed to ensure authenticity and
minimize potential corruption. Your system ROM includes a Failsafe Boot Block that is pro-
tected during the flash process and allows the computer to be restarted in the unlikely event of an
unsuccessful ROM flash.
If the system detects an invalid system ROM during the boot sequence the system will sound
one long and three short beeps, flash the three keyboard LEDs twice, and display a recovery
mode message on the screen. To recover from the Boot Block recovery mode complete
the following steps:
1. Remove any diskettes from the diskette drive and turn off power.
2. Insert a ROMPaq diskette into the diskette drive or a bootable CD-ROM into an IDE CD-
ROM drive. (Bootable ISO CDs are available on the Web at www.hp.com.)
3. Turn on power to the system.
4. If a Setup password has been established, the Caps Lock LED will come on to prompt you for
the password. Enter the password.
5. A successful boot and ROM flashing (reprogramming) with a ROMPaq diskette is indicated
by the three keyboard LEDs turning on and a series of beeps rising in tone.
Security Functions
The system offers independent Power-On and Setup passwords for system and data protection.
The Power-On password protects the computer from unauthorized access by prompting the user
for a password during power up. The Setup password protects the computer from unauthorized
or inadvertent reconfiguration of legacy device resource settings or ROM flash upgrade by
prompting the user for a password prior to entering the Setup Utility.
To establish a password:
1.
Turn on or restart the computer. If you are in Windows, click
Start > Shut Down >
Restart the computer.
2.
As soon as the computer is turned on, press and hold
F10
until you enter Computer Setup.
Press
Enter
to bypass the title screen, if necessary. If you do not press
F10
as soon as the
computer starts, a restart will be necessary.
3.
Select Security, then select Setup Password or Power-On Password and follow the
instructions on the screen.
4.
Before exiting, click
File > Save Changes and Exit

Selects active data transfer mode.
Options are PIO 0, Max PIO,
Enhanced DMA, Ultra DMA 0, and
Max UDMA.
Translation Mode (ATA disks only) Selects translation
mode to enable the BIOS to access disks partitioned and
formatted on other systems and may be necessary for
users of older versions of Unix. Options are: Automatic,
Bit-Shift, LBA Assisted, User, and None.
NOTE:
The translation mode automatically
selected by BIOS should usually not be changed.
Translation Parameters (ATA disks only) Allows you to
specify disk parameters logical cylinders (max. of 1024),
