Hi guys,
So I am in final steps of building my 486, latest step being swapping old an noisy 2GB HDD for CF-to-IDE disk.
I followed several guides for partitioning, formatting and installing DOS 6.22, eventually making it boot.
I was happy as a clam, with the computer being all fast and quiet - right up to a point when I tried running any program, other than Norton Commander - with most EXE, the computer freezes on startup, or goes to reboot straight away. Some are not locking up the computer but refuse to run with various error messages.
There are just handful of EXE files which could be run, majority do not, showing symptoms described above.
I tried reformatting and reinstalling DOS, but same issue follows.
First I though that my MB (HOT419 R2) or I/O controller has some issues with the CF-to-IDE disk, but same behavior follows in different setups (on-board IDE board, different CPU, RAM, BIOS version and settings). So I figured I am missing some important step in SW setup.
Can you help me get to the bottom of this?
My system:
CPU AMD 486DX4 100Mhz
MB HOT419 R2
64MB RAM (4x16MB SIMM 72pin)
SPEA V7 Mirage graphics card
Goldstar I/O controller
SB 16
FDD, CD-ROM (on slave)
For CF-to-IDE, I am using Delock bracket board.
I have desoldered the activity LED and soldered in some pins for connecting the case LED.
I have not messed with onboard jumpers on the Delock board in any way
Thanks, I appreciate any help,
Vojtech
