    I changed a speed setting in bios and now system will not boot up, I get "BIOS ROM checksum error" & "detecting floppy drive A media..." but it never finds anything on the floppy disk. I have a msdos bootdisk with awdflash utility and the bios bin file on it in the drive but it does not read it or execute the autoexec.bat file i wrote to run the bios flash utility. I have disconnected all drives except the floppy "A" and removed all but one memory DIMM (512mb) I have tried 2 other, known good Floppy drives. Nothing works to make the bios flash? I have even tried removing the video card and flashing it blind. It spins the floppy but never does more than that, regardless of what floppy drive is connected. All the usual cmos clearing, battery removal etc does nothing to help.

When i switch on computer the screen comes up with Drive1 not found:SerialATA,SATA2 Floppy diskette seek failure Strike the F1 key to continue,F2 to run the set up utility

Ok. It sounds like something happened inside the BIOS settings for the machine. Most PCs todays do NOT have 3.5" floppy disk drives (drive A) anymore. There is a place in the BIOS where you select the type and size floppy drive connected as drive A. One of the options is "NOT INSTALLED" . If your BIOS setting shows a floppy drive and there is none present, every time you boot up it will give the Floppy disk seek error you mention. Next time your boot, select the F2 option. Check to see if a floppy drive is selected. If so, change to NOT INSTALLED. Also, there may be on the advanced page an option of "Floppy seek at bootup" . You can disable this and that will help as well.

I kep getting an error on bootup about A: configuration in bios I can not boot the machine due to this problem. Also, I need to boot from UB drive, FINALLY got into bios, but it is still giving me the...

Is there a floppy disk in the A: drive? That "port" is usually reserved for a floppy disk, either 3.5 or 5.25in. You probably need to disable the floppy drive in the BIOS.

If you are receiving this on bootup. First check and see if you have a floppy drive, if you do NOT then it is a bad setting in your BIOS.

At bootup, use the key listed to allow you access to the setup. Under diskette drive you will need to turn it to NOT INSTALLED, NONE, or OFF, whichever your BIOS supports. After you do this you should not get this error.

If you DO have a floppy drive, then you need to check the power and data cables they are probably loose from either the drive or the motherboard (data cable).

Floppy disc driver

You need to find system informaton and drives in the bios. You have to tell the computer what kind of drive you have. When you are at the right place you will see a drop down menu choosing your drive type. Newer computers do not support floppies and have memory card readers instead. If this is the case you will have to get a USB floppy drive.

Need to reset the password

Make A boot disk from a working Windows 98 machine. After you make the boot disk, copy the MS 'debug' to the floppy. 
Boot the laptop from the floppy.(this might not be possible due to a setting in the BIOS.) 

Search online for MS Debug +clear CMOS 
Run the Debug program and type in the commands exactly as written. 

reboot, and you should be able to go into the BIOS by holding F2.  

That's it. 

If you can't boot from the floppy, remove the hard drive. the computer should boot from the floppy, no matter what the BIOS setting is.

You may have to get a new bios file. To do this you will need to find the newest bios version for your motherboard. Download it, copy it to a bootable floppy and "flash" your bios.

Lost boot up floppy

Two things may have happened:

The hard drive has failed, so it is trying to boot from the next available drive (floppy)


The BIOS battery went dead, and has reset to factory defaults and it trying to boot from the floppy drive.

If you can get into the bios ( hold F1+ F2+ CTRL+ ALT+ ESC after you turn it on), look for anything related to "boot" and change the boot drive order. If you find it, be sure to save the settings, then restart.

**note**, alot of the old computers have a very primative BIOS, and you may not be able to change the boot order.

Let me know if this gets you into the bios, as they changed "how" to do it over the years.
