I was loading some networking drivers on my IBM Thinkpad 600 and got a fatal error message that told me I had to reload the operating system. I then did a very stupid thing by selecting only the CD-ROM to boot up in the bios setup configuration menu. (I wanted the machine to autostart the cd on bootup prior to WIN98 loading...I wasn't able to reload the OS with the OS already operating). Now I can't boot from a good startup floppy disk (I verified the disks on another machine) nor is does it recognize the harddrive at bootup...it only reacts to the bootable cd rom as I configured it.
The problem is that I cannot get the bios menu to come up again by pressing F1 prior to the machine posting. I get an error code I9990305 at bootup (which means there is a Fixed boot sector error, no operating system installed, the IBM site says that it means there is no bootable device.). I push F1 as I startup the laptop... I then get an animation of a floppy going into a the floppydrive. When I push f1 ( as indicated by the animation) I get the I9990305 error.
If I use the recovery disk provided by the 2nd source provider, I can load the boot drivers w/ or w/out cd support. I can then access the b: floppy drive and the c: harddrive and the cd rom drive.
I tried to reflash the bios, thinking that it would default the boot sequence back to hhd, floppy, cd but I get a "image file corrupted" error when I am extracting the flash bios program I downloaded from the IBM site (spsdib54.exe 628,030 BIOS - System Program Service Diskette)
I reformatted the c drive with format c: /s, then loaded windows 95 from the rescue disk. When I try to manually start windows from the c drive (after booting from the CD rom), I get an error message saying the certain files are missing.
I tried loading WIN 98SE but when it comes time to reboot, I get the same problem with the I9990305 error.
Help!! How can I get back to the bios menu? Life was simple back then!!
