Hello,
I have many questions, but I'll start by the most essential one. SvarDOS seems to ignore my UMB, even with the parameter DOS=HIGH,UMB in config.sys. On my 386DX40, I usually use the RDOSUMB utility to use shadow ram as umb. I run the utility in my config.sys, and this gives access to UMB and it is reported by the Mem command (in FreeDOS/PC DOS). But in SvarDOS, mem doesn't report any UMB, any everything is loaded in conventional memory.
I also tried with an alternative, by using my Bocaram AT Plus expanded memory ISA card. I load the Emm driver, with QRAM.SYS. Both drivers load correctly, but again, nothing is loaded in UMB, and the MEM command display 0 k in UMB, despite the 16K of UMB at DC00h made available by QRAM.
So... How to I enable access to UMB in SvarDOS?
Thanks!
Edit: Sorry for the typo in the title, I can't correct it.
If you use the EDR-DOS kernel, make sure to put DOS=UMB *after* the DEVICE= line that provides the UMBs. DR-DOS appears to process (d)config.sys differently than FreeDOS and MS-DOS.
