Jumper Settings on Anigma BAT ====================================================================== 1. General Information This motherboard is used in 486 systems by Gateway 2000. It is made by Anigma and is referred to as the BAT or Anigma BAT or BAT486IP (not to be confused with Anigma BAT2). The original BIOS supports large drives up to 2.1GB (4095 cylinders). The drive type must be set to AUTO for drives over 504MB. The Promise EIDEMAX card should work to support drives over 2.1GB. See section below on using EIDEMAX. There is a problem with using the Intel Pentium Overdrive CPUs on this board. With a POD installed, the system will hang on any DMA access. This includes any access of the diskette drives. Since this board also uses DMA for hard drive access by default, hard drive access will not work with POD installed if set to DMA in CMOS setup. At Gateway2000's request, we have created a patch for the original BIOS to fix this problem. This patch is available on our web site. We do not currently have a BIOS upgrade for this board and will probably not develop one. If the patched version of the BIOS is installed, the BIOS version will be indicated on power-on as 1.03.MFI01 (the version will not appear differently with a reset or CTL-ALT DEL reboot). If the POD is installed, it will not be ID'ed correctly by the BIOS on bootup. The text "operating at over 100 MHz" will be displayed if the board is set to 33 MHz. The text "operating at 66MHz" will be displayed if the board is set to 25MHz. The type of CPU will not be indicated. ====================================================================== 2. Using the Promise EIDEMAX on the Anigma BAT Motherboard As far as we know, GW2K normally supplied a PCI IDE adapter card for the hard drive on this system. This would probably be due to the limitation of the onboard IDE, which is limited to Standard PIO Mode, since there is no local-bus onboard IDE controller chip. (The BAT board can also use DMA for hard drives). The EIDEMAX should work fine with hard drives plugged into the onboard IDE port as long as the add-in PCI adapter is removed, the IDE port on the EIDEMAX is disabled, and jumper J41 is set to pins 1-2 for IRQ14 (pins 2-3 is IRQ15). J41 is located between 2 of the ISA slots. The Promise EIDEMAX can also be used as a secondary IDE interface in addition to the onboard primary interface. The EIDEMAX should also work as a primary interface as long as J41 on the motherboard is set to IRQ15. All hard drives over 504MB should be set to Type 1 in CMOS setup if using the EIDEMAX card. ====================================================================== 3.
