no i am not using isa_readb() etc. infact i am accessing this area 0xA_0000
as Memory/IO in memory mode. i have seen the pci bus transactions, its
generating memory read and memory write commands. but due to some reason
that is still *unknown* to me generates master abort. i always get master
received master abort. could you tell me what could be the reason?
