>Description:
My system is Texas Instruments' notebook
TravelMate 5000, Pentium 75 MPU, 16 Mbyte of RAM,
one EIDE hard disk, one floppy disk.
An atemption to boot from either boot or boot-pao fails
after probing all the devices.
Last messages on the screen are:
...
npx0 on motherboard
npx0: INT 16 interface
PC-Card Cirrus Logic PD672X (5 mem & 2 I/O windows)

Multiple ASCII 0xf characters appear on half screen
and system hangs forever.
BTW, 2.1.5 and 2.1.7 work just fine on my system.
>How-To-Repeat:
Just boot from 2.2.1-RELEASE floppy any TravelMate 5000
>Fix:
Don't know yet.

 I am forwarding the exchange between the PR originator and me.
 
 Does i586_bcopy() have problems with certain steppings/models of
 Pentium?

 Try setting the configuration flag of npx0 to 0x01 in the User
 Configuration menu. This will prevent some Pentium-specific
 optimizaion code in the kernel code, which is causing problems in some
 systems.

 Thanks a lot. It boots now.
 BTW, my cpu is genuine Intel's Pentium 75 MHz, why does it
 not understand some Pentium-specific code ?
