I could not find the program I originally used to create a bootable CD. However you do it, you should be able to make it not to start Windows directly, but to boot into DOS mode. You may need to press F8 or something while booting. I am not using that ThinkPad anymore, so I can not give you any additional details. Once you get to the command prompt, just run the no-1802.com (I think you can run it from the hard drive, it does not have to be on the CD you boot from.)
ThinkPad 1802 Error Fix
I encountered similar problem that Lawren had.However, I was able to use my USB floppy drive and boot from there to run no1802.com.If the USB floppy drive does not work for you, you may want to try a directly attached floppy drive (in place of the CD/DVD drive slot) and go from there.
Worked great on an X31 type 2884. I created a USB stick formatted using the instructions/files at -a-bootable-usb-thumb-drive,copied no1802.com to the drive, set the Thinkpad to boot from the USB HDD, and it worked the first time! ? Thanks for the tip.
Worked great on my A31. All I did was put it on a floppy, book my laptop into DOS mode using an old W98 Boot Disk, inserted the floppy with the no1802, ran the program and no more error! This was much easier than the ethtool method I used on my old thinkpad and the command-tab instructions floating around. Thanks much!
The no-1802 program does not reflash or actually repair the problem, it is simply a work-around that changes a BIOS setting which is inaccessible from within the user accessible BIOS settings. If the CMOS battery dies or if your BIOS is reset, your BIOS will again give the 1802 Error. If the CMOS battery dies, Replace the CMOS battery first, then Run the no-1802 program again and you should be fine for more years until the CMOS battery dies again.
Worked and tested on IBM ThinkPad T42 with intel 2200BG Wireless card! Just download CD image from this site -tab.com/2006/02/26/thinkpad-1802-error-fix/and burn it.Required disable network adapter from bios before boot CD,after boot from CD and type no-1802 enable card from bios ,thats it.
The Power-On Self Test, or POST, is the part of this process that determines whether hardware is operating correctly. If an error occurs at this stage, the PC may shut down before providing a video display. Motherboards will make a series of beeping sounds, use color-changing LEDs, or show an error code on a built-in display to help you diagnose the issue. 2ff7e9595c
