[comp.sys.ibm.pc] Problems with DMA/IRQ init

jh@materna.uucp (Juergen Hackenbroich) (07/19/89)

Hi netlanders,

in the last time we discovered some special problems with the
newest at clones.

The normal way of initialising of interrupt vectors and dma units does
not work any more on certain machines.  Most of them are 386 machines. 
The behaviour is very funny: some of them can never run our program
(they die completly) and some can run it once and only once.  We suspect
a trick which must be used on certain chipsets, but all manufacturers
say "we are compatible". 

Thanks for any comment
