BIOS Need to boot up on CD-ROM ...... Setting in BIOS are not letting me do this. Where is is located to turn on the Floppy and CD ROM in the BIOS?

it's not locksum ,its Check SUM or CRC errors.
what OP, are you running,? windows what. i guess.

the CMOS battery just died.
install a new one.
all puters this old do that, the battery is good for 7-10 years,
and all fail.
DO NOT FLASH your BIOS, fix the real problem first

when the battery dies, all our bios setting were lost
including boot device, and order
fix battery
then go into BIOS and put back boot order.

What happens when you turn the computer on?

If the bios is working enough to enable you to boot from a CD download the new bios from asus along with there AFUDOS.exe flash utility and make a bootable CD and copy both to it.

If the bios is completly none functional you should be getting this msg when you turn the computer on,
Boot Block Compatible Version Ver .010
Bad BIOS checksum. Starting BIOS Recovery
Checking for floppy . .
Floppy not found
Checking for CD rom . . .
CD not found
Checking for floppy . .
Floppy not found
Checking for CD rom . . .
CD not found

Repeat adinfinitum.
If this is the case you need download the most recent BIOS from compaq and either copy it to a bootable CD if you have this capability or buy a floppy drive for $5 and make a bootable floppy on a working computer and copy this BIOS file to it. Then rename the bios file to A8N32SLI.ROM.

You may not even need make the floppy bootable but I would just in case.

Stick the floppy in the drive turn the computer on and you will see

and happy days will be here.

iat the time of boot a message as follows is displayed
"boot block compatible version .005"
bad bios cheksum. starting bios recovery
checking for floppy. floppy not found
checking for cd rom. cd rom not found"
.. using asus motherboard

2 options:

1. create a bootable cd with the bios rom file, and a dos based flash utility (included with bios download). Boot to cd and flash.
2. Connect a usb floppy drive and create bootable floppy. Copy rom file and flash utility to floppy, boot to floppy and flash......option 2 may be easier if you are not familiar with creating bootable cd's.......Let me know if this helps or not.
   

try to go to bios setup and change the boot priority for the devices, by setting first priority to your Hard Disk , and then your CD Rom and last to the floopy disk..

Floppy works right? So you need to boot from floppy disk, install USB drivers in DOS and then access an external USB device... whew. OK, so getting a dos 6.22 boot disk is easy, then you have to load a DOS-level USB device driver that 'recognizes the chipset in your USB controller/port and can turn it 'ON'

Go here and READ ;-) They have everything you need (except for my expert help)

Good luck!
P.S. There are many DOS-level drivers out there, if you don't find one for your PC, make a noise and I'll see if I can help

You need to go to the website of whoever made the motherboard and get the BIOS flash utility and the BIOS binary file to update your BIOS. Make sure you get the right one, as using the wrong one can render your motherboard worthless. The BIOS file has to be the exact match. There is no such thing as close in this situation.
If you are not sure of the exact make and model, get te free Belarc Advisor from http://www.belarc.com
The BIOS chip holds information about your motherboard hardware. It is reprogrammable. It uses what is known electrically erasable read only memory. This is also called Flash memory. Reprogramming is called flashing. When you flash the BIOS, all data is erased, then the new data is written. The flash utility will most likely allow you to save the old contents, but you might have an extremely tough time recovering from an improper flash. You'll also probably need a couple of floppy disks, one of which may have to be bootable. If you need a bootable floppy disk, you can get an image file from http://www.bootdisk.com.

You need to use floppy disks (called boot disks) to boot DOS with cd-rom drivers, because the win98 cd isn't bootable by default.

I suggest you to go to http://www.bootdisk.com/bootdisk.htm and grab the respective windows 98 boot disk.

You will need a functional computer to write the disk image into the floppy.

After that put the boot order in BIOS as floppy first.

Once you see DOS prompt A:\> just access your cd-rom drive like d: or e: and then type install

Does someone already fix this problem??????

on a friend's Windows 98 SE or Windows ME computer, create a floppy "Startup disk". Insert in your pc floppy drive and turn on. If floppy drive was not accessed, then get to BIOS and ensure "Boot from floppy drive" is set prior to "boot from hard drive". Once at first screen, select "Boot with CD-ROM driver". Insert CD-ROM and initiate entire re-install of Windows. Windows may do some self-restarting. At first restart do this: get to BIOS and ensure "Boot from hard drive" is set prior to "boot from floppy drive".
