Hi,

Recently I decided to load OS/2 WARP Version 3 operating system onto my 486DX-100 machine.

As soon as I boot the system using Disk # 1 (Install disk) on drive A, I get the following message:

"The file OS2KRNL is not acceptable.  Insert a system diskett and restart the system".

My system configuration is as follows:
Generic 486/100 PC compatible
AMI-BIOS
Identification number 40-0130-009999-00101111-080893-ALI1429G-H
DTC-EIDE card
16MG mem

Can anybody help?  Greatly appreciated.

The brand of the motherboard is a generic one.  I currently use the system using Windows 95.

i had a problem similar to this. my 486 board has a flaw in it.
if write thru cache( or was it write back) is enabled the floppy cannot be booted. if i need to boot from a floppy i must pick the other cache method.

Thanks to Clark R. Tompset at Southwest Cyberport.  He gave the following solution and it resolved the problem:

“Try turning off  the External/Internal caches in the bios.  You should be able to install the core system.   When it does the first boot, go back into the bios and re-enable the caches.  Note--- system will run slow while the cashes are off.  I had this problem with a AMD dx4-120.”

It worked fine with me too

There are two causes of this problem.

One, like other experts says, it's the motherboard hardware cache or motherboard itself has a flaw in it caused the error calculation error.

Second, if you have noticed or maybe you have not, Pentium or 486 chips upgraded into FASTER speed <Over drive?> can cause those problems.  If your CPU is DX4/100, you can try to connect IBM or INTEL for solution.  If your CPU is one of those "OVER DRIVE" which makes 386 -> 486, or 486 -> 586 one of those turbo charger, if your installation is smooth, errors will occured once you are using it.  Nevertheless, if you are one of those turbled CPU, try to reduce the CPU clock back to normal.  <For example, my 486/80 always have problem, untill I switch back to 486/66 it's normal speed.>

I hope this helps?
