I’d be appreciated if you help me to find additional information about nice early 386 PC from 1990: Wearnes Boldline 386-33. Especially motherboard jumper settings description.
I was unable to find any useful information except some ads in computer magazines.
Please see attached MB photos, ROM BIOS. I’ll create a better photo later, it can be upload to ultimateretro DB later.
ROM-BIOS AMI Wearnes Automation (Pte) Ltd Boldline 386-33 Series
BIOS ID string is: SAMI-2112-121589-KF
PC came with CPU, cache controller and 4 Mb RAM populated on board, no display adapter, HDD and peripherals and was able to boot only with VGA card installed. After Dallas replacement I was able to configure BIOS and boot from hard drive.
For this moment it works fine as it is, but all my attempts to install FPU was unsuccessful. I have tried to install 4 different FPU from Intel, Cyrix, IIT, ULSI without any success. All this FPU can be correctly detects by NU or PC Config diagnostic utilities but fall during the tests and benchmarks. MB also didn’t see additional SIM modules installed. I suppose that memory configuration should set by the DIP switches SW1 or SW2 as BIOS has limited options, as well some FPU settings like frequency may be also configured via these switches.
For sure I will try to play with these switches and find what options can be configured such display type, COM, LPT settings and so on. Will keep update about the progress.
