Hiya!
I have a couple 16mhz 286 motherboards with the Headland HT12/A chipset and I was wondering if there is a UMB driver for it.
I have tried "The Last Byte Manager" that provides up to 64kb of UMBs for the HT12 chipset but all it does is hard-lock both machines... 😢
Perhaps there is a HT12 chipset without the /A and that's why it doesn't work 😕
The HT12MM.SYS EMS driver does work and provides EMS RAM but no UMBs. Is it even possible?
Here are some photos from the chipset, BIOS screen and TLB manager:
and here is the MEM output with HT12MM.SYS loaded to provide EMS:
Any ideas/tips?
TIA for any help/info! 😊
