"SFB - KB3MM" wrote in message ... This is from the Wn 98 Resource Kit. Search for Locked and then click Installable File System from the list: The 32-bit VFAT works with a 32-bit, protected-mode cache driver (VCACHE). This driver replaces the 16-bit, real-mode SMARTDrive disk cache software provided with MS-DOS and Windows 3.1. The VCACHE driver features better caching algorithms than SMARTDrive, to cache information read from or written to a disk drive. The VCACHE driver also manages the cache pool for the Universal Disk Format File System (UDF) and the 32-bit network redirectors provided with Windows 98. Another big improvement in VCACHE over SMARTDrive is that the memory pool used for the cache is dynamic and is based on the amount of available free system memory. Users no longer need to allocate a block of memory as a disk cache. The system automatically allocates or deallocates memory used for the cache, based on system use. For example, as you perform a large number of activities on the network, Windows 98 increases the size of the cache. As network activity decreases and more applications are started, Windows 98 decreases the cache size. Another improvement made to VCACHE in Windows 98 is the ability of VCACHE and the memory manager to execute applications that are present in the cache, directly out of the cache memory. This is referred to as cache mapping and improves the efficiency of memory utilization. Remember you can monitor locked pages via System Monitor. And the point?? |

Maybe it is out of favor now, but that is an old programmers' description of data files, especially dynamic ones. Many of the files just lay around the DASD farm unless you wake them up. :-) Has to do with the [once?] anthropomorphism of the computer. Just curious here, if I said that memory had apparently been walked on causing the error, would that seem quaint or unintelligible? FACE |

Maybe he said that because VCACHE buffers ARE a dynamic and living thing
