Purpose

DosQueryABIOSSupport returns flags that indicate various basic hardware configurations.

Syntax

#define INCL_DOSMODULEMGR
#include  os2.h>

APIRET APRENTRY DosQueryABIOSSupport

(ULONG Reserved)

Parameters

reserved (ULONG) input

Must be set to 0L. No other value is defined.

The following flags are returned

HW_CFG_MCA

0x01
HW_CFG_EISA
0x02
HW_CFG_ABIOS_SUPPORTED
0x04
HW_CFG_ABIOS_PRESENT
0x08
HW_CFG_PCI
0x10
HW_CFG_OEM_ABIOS
0x20
HW_CFG_IBM_ABIOS
0000
HW_CFG_PENTIUM_CPU
0x40

Example Code

int main(int argc, char *argv[], char *envp[]){
   APIRET flags;

   flags = DosQueryABIOSSupport(0L);

   printf("H/W config  %08x\n",flags);

   if (flags   HW_CFG_MCA)             printf("            0x01 => MCA Bus\n");
   if (flags   HW_CFG_EISA)            printf("            0x02 => EISA Bus\n");
   if (flags   HW_CFG_ABIOS_SUPPORTED) printf("            0x04 => ABIOS Supported\n");
   if (flags   HW_CFG_ABIOS_PRESENT)   printf("            0x08 => ABIOS Present\n");
   if (flags   HW_CFG_PCI)             printf("            0x10 => PCI Bus\n");
   if (flags   HW_CFG_OEM_ABIOS)       printf("            0x20 => OEM ABIOS\n");
   if (flags   HW_CFG_PENTIUM_CPU)     printf("            0x40 => Pentium or Higher CPU\n");

   return 0;
}
