It translates to something as below. I don't know what it does though,
as I have zero knowledge of the SMI register.
#define SMIC 0xB2
#define SMID 0xB3
int val;
/* acquire mutex for this operation here */
outb(SMID, 0x04);
outb(SMIC, 0x95);
while (inb(SMIC) != 0)
;
val = inb(SMID);
/* release mutex for this operation here */
