QNX USERS QNX2 and QNX4

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.
question:
The problem stems from the hard drive? with the video card? from the hard disk controller?

Thanks.

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.
