Hi,

ROM check sum errors happen after a failed attempt to update the BIOS or more frequently, when the system's RAM is bad. (The check summing happens when the main POST program is unpacked from ROM to RAM - so it fails when either is bad.)

So check your BIOS chip or RAM.

Thanks

Ntldr is missing at startup


To fix your problem please follow the below steps.
1. Locate your Windows XP/2000 installation disc and place it in your CD/DVD ROM drive. If you don't have this disk, then you cannot proceed further.
2. Restart your computer.
3. When the computer restarts press any key on your keyboard when you are prompted, "Press any key to enter setup." Most computers are configured to boot to another device other than a hard drive. Since the Windows XP/2000 installation disk is bootable, you should see the prompt. However, if you don't see the prompt you may need to change your boot priority in your BIOS. To do so, enter the system BIOS by following the onscreen instructions upon startup. Then navigate to the Boot Priority menu and modify another device, such as a CD-ROM to boot prior to the hard drive. Then reboot your computer.
4. After you have pressed any key, the Windows XP/2000 setup screen will appear. After loading, press the "R" key to repair the Windows installation. The screen will appear black. The computer requests which installation you would like to log in. Generally speaking, press "1" and "Enter." If you have more than one hard drive or more than one partition, the procedure may be different. You must know which hard drive or partition your Windows operating system is installed in. You are subsequently prompted for a password. If you haven't set up one up, you can just leave the query blank and press "Enter." The phrase "c:\WINDOWS>" and a blinking cursor subsequently appear.
5. Type "copy d:\i386\ntldr c:\windows" (without quotes), where "D" is the letter of your CD/DVD ROM drive (your optical drive may be different, especially if you have more than one). Eject the CD from the drive and type "Exit" (without quotes) to restart your computer. The NTLDR file will be copied from the installation disc to your hard drive.
Thanks for contacting Fixya. Have a good day.

BIOS Beep Codes
Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem. The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (a faulty video card or no card installed) or if an external ROM module does not properly checksum to zero.
An external ROM module (for example, a video BIOS) can also issue audible errors, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that external device.
There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of the screen (using both monochrome and color adapters).
If POST completes normally, the BIOS issues one short beep before passing control to the operating system.

What happens inside the PC between turning the power on and you see the desktop on the screen?


  1. The internal power supply turns on and initializes. The power supply takes some time until it can generate reliable power for the rest of the computer, and having it turn on prematurely could potentially lead to damage. Therefore, the chipset will generate a reset signal to the processor (the same as if you held the reset button down for a while on your case) until it receives the Power Good signal from the power supply.
  2. When the reset button is released, the processor will be ready to start executing. When the processor first starts up, it is suffering from amnesia; there is nothing at all in the memory to execute. Of course processor makers know this will happen, so they pre-program the processor to always look at the same place in the system BIOS ROM for the start of the BIOS boot program. This is normally location FFFF0h, right at the end of the system memory. They put it there so that the size of the ROM can be changed without creating compatibility problems. Since there are only 16 bytes left from there to the end of conventional memory, this location just contains a "jump" instruction telling the processor where to go to find the real BIOS startup program.
  3. The BIOS performs the power-on self test (POST). If there are any fatal errors, the boot process stops. POST beep codes can be found in this area of the Troubleshooting Expert.
  4. The BIOS looks for the video card. In particular, it looks for the video card's built in BIOS program and runs it. This BIOS is normally found at location C000h in memory. The system BIOS executes the video card BIOS, which initializes the video card. Most modern cards will display information on the screen about the video card. (This is why on a modern PC you usually see something on the screen about the video card before you see the messages from the system BIOS itself).
  5. The BIOS then looks for other devices' ROMs to see if any of them have BIOSes. Normally, the IDE/ATA hard disk BIOS will be found at C8000h and executed. If any other device BIOSes are found, they are executed as well.
  6. The BIOS displays its startup screen.
  7. The BIOS does more tests on the system, including the memory count-up test which you see on the screen. The BIOS will generally display a text error message on the screen if it encounters an error at this point; these error messages and their explanations can be found in this part of the Troubleshooting Expert.
  8. The BIOS performs a "system inventory" of sorts, doing more tests to determine what sort of hardware is in the system. Modern BIOSes have many automatic settings and will determine memory timing (for example) based on what kind of memory it finds. Many BIOSes can also dynamically set hard drive parameters and access modes, and will determine these at roughly this time. Some will display a message on the screen for each drive they detect and configure this way. The BIOS will also now search for and label logical devices (COM and LPT ports).
  9. If the BIOS supports the Plug and Play standard, it will detect and configure Plug and Play devices at this time and display a message on the screen for each one it finds. See here for more details on how PnP detects devices and assigns resources.
  10. The BIOS will display a summary screen about your system's configuration. Checking this page of data can be helpful in diagnosing setup problems, although it can be hard to see because sometimes it flashes on the screen very quickly before scrolling off the top.
  11. The BIOS begins the search for a drive to boot from. Most modern BIOSes contain a setting that controls if the system should first try to boot from the floppy disk (A:) or first try the hard disk (C:). Some BIOSes will even let you boot from your CD-ROM drive or other devices, depending on the boot sequence BIOS setting.
  12. Having identified its target boot drive, the BIOS looks for boot information to start the operating system boot process. If it is searching a hard disk, it looks for a master boot record at cylinder 0, head 0, sector 1 (the first sector on the disk); if it is searching a floppy disk, it looks at the same address on the floppy disk for a volume boot sector.
  13. If it finds what it is looking for, the BIOS starts the process of booting the operating system, using the information in the boot sector. At this point, the code in the boot sector takes over from the BIOS. The DOS boot process is described in detail here. If the first device that the system tries (floppy, hard disk, etc.) is not found, the BIOS will then try the next device in the boot sequence, and continue until it finds a bootable device.
  14. If no boot device at all can be found, the system will normally display an error message and then freeze up the system. What the error message is depends entirely on the BIOS, and can be anything from the rather clear "No boot device available" to the very cryptic "NO ROM BASIC - SYSTEM HALTED". This will also happen if you have a bootable hard disk partition but forget to set it active.

I can not boot my hp pavilion a1720n. I get the error message below. I have opened up the case and moved the jumper and replased the battery. Award Bootblock Bios V 1.0 2000, Award Software Inc Bios Rom...


First of all your problem is caused by the hard disk - it has died and must be replaced. Second you are booting from the wrong disk Hiren's disk is a very specialized system analysis and recovery disk, it's not a Windows reinstall one. You should use the disks that came with your pc for that, after you replace the hard disk. Finally you should check the memory sticks, the low memory warning appears only when it way low, less than 256MB. If this is really how it is then you should buy more.

I have an ei system 103a desktop i have had to sytem restore now when i turn pc on it tells me to press f1 to start windows i have tried going into the bios and boot from hardisk but still have the problem...


The 'Press F1 to continue" message is a result of an error caused as the BIOS does its hardware checks during the boot process.

The BIOS boot process (bootstrap) preceeds the loading of the operating system.

The most amusing example of this occurs if you unplug a ps2 keyboard, 
1, it generates the error
2, pressing F1 does no good because the keyboard is not plugged in.
3, if its ps2, you will need to do a hardware reset after plugging the keyboard in again.

The bios can be set to 'halt on'
'no errors' which will stop the error message appearing.
'keyboard errors' see above
'all errors' any hardware failure detected by the bios will halt the boot process and give the above message.
