First post, by amigasith
first time poster here, so please forgive me if this is a stupid question 😀 After playing with Amigas for the last couple of years, I recently re-discovered my love for the 486 era and so I bought a bunch of 486 boards to tinker with, including a Shuttle HOT-433.
It had an empty Dallas and so I replaced it with a nice PCB from a fellow a1k .org forum member. This PCB is based on the well-known BENCHMARQ chip, which seems to work just fine. The CMOS battery state low message is gone now and the board saves time and other settings just fine, therefore I think everything BIOS-related works as expected. BIOS revision is AUS2C by the way.
What really puzzles me, however, is the HUGE delay until the board actually resets when I press Ctrl-Alt-Del. I measured it and it literally takes 10 seconds (!) until the reset actually happens. All the other boards that I have reset instantly after pressing Ctrl-Alt-Del. So my question for you guys is: Is this (1) normal for a Shuttle HOT-433 board or is this perhaps (2) a known issue that can be fixed somehow or (3) do you think the board has a hardware issue?
Any hint is greatly appreciated!
EDIT: I forgot to mention a couple of things:
- I tried several different keyboards, but the reset behavior is always the same: I press Ctrl-Alt-Del and then it takes 10 sec until the reset actually takes place
- I tried different PSUs, but no change either
- I re-seated all socketed chips, but to no avail
- The keyboard itself reacts promptly when typing either under DOS - I'm only using a floppy disk drive at the moment - or in BIOS menus
- Hardware reset works instantaneously
- Electrolytic caps still look fine - no visible bulging and / or spill
