DOS ain't dead

Gigabyte GA-B75M-D3V quick DOS test, XMS size detect.problem (Users)

Hi,
I have a chance to test quite new mobo Gigabyte GA-B75M-D3V with UEFI for a day or two. CPU is intel Pentium G860 Sandybridge, chipset (PCH) intel B75 and 4GB RAM. It has integrated VGA - intel HD gfx in CPU core with configurable VRAM size (par of syste4m RAM - I allocated 256MB). It has also one LPT, COM and PS/2 port.

I just done some quick tests using my utils to see how well it works under DOS.
First you can look at new UEFI SETUP interface. It run in gfx mode and use mouse. http://rayer.g6.cz/1tmp/GA-B75M-D3V/SETUP/. There are some legacy settings like SATA IDE mode vs AHCI, emulation of port 60/64 for USB KBD, mouse emulation, loading ROM and UEFI ROM modules from peripherals, setting of LPT mode, address and IRQ. There's no advanced. setting for COM ports. I found the setup has quite poor set of settings compared to my old classic Award BIOS 6.00.

I ran FreeDOS and MSDOS on it without problems. Kbd and mouse emulation works quite well. Even when set IDE mode my tool SMB /ide was unable to detect HDD on legacy port. But it worked when I installed Windows XP.

One issue I observed was that JEMMEX and HIMEMX detected wrong XMS size - only 0,5GB instead of 3,x GB like MS himem.sys from Win98 did. I tried varios options for both but I was unable to increase detected XMS. Japhets, could I help you with providing some further debug?
See all my logs here: http://rayer.g6.cz/1tmp/GA-B75M-D3V/LOGS/

I was very satisfied with VESA speed, both for BS and LFB mode when MTRR was enabled it blits incredibly fast :) Also I should mention that VBE supports widescreen VESA modes (I hate it but someone with such LCD may like it :)

I will also try to run Win98SE on this machine for test. Final will be Win XP for the user as he required.
