Frequently Asked Questions and their answers in connection with CONFIG Q) Config says my computer has a POPAD error. Is it defective, do I have to replace it? A) Under certain conditions the machine instruction POPAD does not restore the EAX register afterwards. The error affects only 386 processors and was only discovered around the middle of 1990 and affects nearly all processors from Intel and AMD. The very newest versions from Intel at least have been corrected. The error is known to software developers and the instruction is only implemented so that the error does not occur. Don't worry about it, my computer has it too. Q) Why can't the chip set on my board be identified? A) I do not have the required information about every chip set available. Unfortunately I have only a limited selection. Q) The short interval timer on my 66MHz board is claimed not to work! A) The test does not work properly on some boards and gives false results. In this event the test should be deactivated with the switch SKIPTIMERTEST in the INI file. Q) Why does it only show ??? on the hard disk rotation speed test? A) Modern hard disks have on board caches up to 256 KB. In this case a whole track is read into cache per rotation, and the disk is not read on a repeated request. Q) In the memory windows areas are mentioned with 8 Bit access. I have a 386/486, so how come only 8 Bits? A) These memory areas are empty, they contain NOTHING; no RAM, no ROM, no HI-DOS, nothing. If these EMPTY areas are accessed, the access is slow and 8 bit. Q) It says my graphics adapter has an 8 Bit bus. It has in fact a 16 Bit bus, I know, I have seen it. A) These adapters can be used in ATs as 16 Bit or in XTs with 8 Bit. The card decides which mode for itself. Many older cards do not identify the bus correctly and even when in an AT think they are in an XT. When CONFIG says 8 Bit, this will be correct 95% of the time. The speed tests will confirm it: 8 bit cards cannot exceed about 700 KB/sec throughput in text mode. Q) Why are the interrupt allocations shown in the IRQ-Window as the standard values and not the ones actually allocated? A) For safety and compatibility reasons I leave the interrupt controller well alone. Q) Why does CONFIG show a higher speed for data transfer for the hard disk than other test programs? A) CONFIG tests the speed of data transfer by reading ONE track by increasing sector number until a maximum value is reached. With hard disks with hardware caches this represents more the value Cache->Bus->Main Memory than Disk surface->Bus->Main Memory. On older MFM/RLL type hard disks it shows really the speed Disk Surface->Bus->Main Memory. The test 'Linear Reading', implemented since the version 6.4 delivers a realistic value also on newer hard disks for the transfer speed from hard disk to main memory. Q) Why are the speed values for BIOS and DOS character transfer so much higher when I boot the computer without any extra device drivers? A) Many device drivers such as the mouse, screen savers or memory managers latch into the character output routines to monitor them or extend their functions. This leads to a reduction in output speed. In addition, the functions sometimes get so big, that they don't fit all at once into the CPU cache any more. Q) Can't CONFIG display the physical parameters of IDE hard disks as well as the translation parameters? A) No. Q) It shows only a strange sign in the upper left corner of the screen and crashes. A) You have a S3 with 801 or 805 chip. Set VIDEOTEST=NO in .INI file. Q) I'm a registered user, why does the new version not work with my .REG file? A) You cannot switch a sharewareversion to fullversion with your .REG file. Please see the documentation, where to find updates of the fullversion. Q) I don't have a 600 MB large CD for the CD-Benchmark?!?!? A) Change the MinCDsize value in the .INI file. Q) It crashes during the harddisk-troughput benchmark? A) If loaded, disable Hyper-Disk V4.70 cache-program via keyboard. V4.70 seems to be defective, since older versions and other cache- software works propperly with CONFIG.
