There were several brands ( PC-chips ...) , but since it cost more and the average user understood none of that stuff , it was rarely implemented . > CV> *On some computers, you may even be able to use HIMEM.SYS itself as > CV> the UMB provider.* >IMHO not ... with maybe the NEAT chipset from above as an exception. (MS-DOS) himem.sys : no ( this is only an XMS provider ). You would need a 3-rd party UMB provider to use your Neat UMBs ( many share or even free- or Gnu-ware .) , (DR-DOS) hidos.sys : built-in , at least for Neat chipset or equivalent. DR-DOS was always in advance - until they had to throw the sponge . -- Steph' < [EMAIL PROTECTED] >
