memory driver

Hello All! Delta/PHG discovered a glitch in a subject published in Echo 6 and used in Real Commander 1.95, when detecting 1 MB of extensions one bank is not taken into account (it’s strange that after 4 years of operation of the RC no one had discovered this glitch before). It is recommended to update the subject two attached test subprograms. Since writing Real Commander 2.0 is moving slowly due to difficulties With the organization of the modular system, I decided to release a new version for now RC from series 1.9 since in the latest available version it was already collected a couple of glitches. Writers of system software with support for RC RamDisk can safely use the updated version of the driver, focusing on new version of Real Commander. === Cut === VIRT LD IX,#C000 LD HL,RSCT+63 LD B,64 V_R11 LD A,B DEC A CALL EX_RAM LD C,(IX+0) LD(HL),C LD (IX+0),A DEC HL DJNZ V_R11 PUSH AF LD A, LENTABL LD (PAGE),A POP AF LD DE,TABL_PG V_R20 LD A,(DE) CP#FF JR Z,V_R30 CALL EX_RAM CP (IX+0) JR Z,V_R22 PUSH DE LD HL,TABL_PG+LENTABL AND A SBC HL,DE PUSH HL POP B.C.
