QNX 4.25 - how to start on normally system

Since 1995, operate a system of Intel 386DX-33/RAM 8Mb/HDD 300Mb QNX 2.2 release 8, RealFLEX 1.22. About 2 years ago, the system has become hang when viewing reports (trends).
How can I upgrade to a system and really start the QNX 4.25.
I think it is necessary to increase the amount of memory and hard disk.
At Intel D865GLC, D915GAG, 440BX QNX boots
with the output lines at startup
. / altboot…D
and further zagrueka happens.
Here, in our reading that QNX 4.25 supports up to ICH5,
At 486DX100 not loaded.
The problem stems from the hard drive? with the video card? from the hard disk controller?


The ‘D’ is an I/O error of some kind. You probably need a new hard drive. You can use a CF card with an adapter if the current drive is IDE.
