Upper Memory Area (UMA): 384K (3 x 128K)
. = 1K free RAM
H = HGC Hercules Graphics Card RAM (text and graphics)
    excluded in REMM.SYS, /X=B000-BFFF

E = EMS (1-4) frame pages (4 x 16K = 64K); REMM.SYS -> Rampage 286 card
    Strangely, you can put the EMS page frame on A0000, although this is not 
    possible according to the manual, see manual page E-8.
1 = QRAM High RAM (Region 1); (2 x 64K = 128K); QRAM.SYS

R = Motherboard ROM BIOS
h = High Memory Area (HMA); HIMEM.SYS is installed -> DOS=HIGH
u = free, but unusable in an AT class PC
