- On this page, INFOPLUS will attempt to identify the type of computer you
- have, and the ROM (Read Only Memory) that it contains.
-
- NOTE!!: If you are using QEMM 6, and are using the Stealth option, some
- ROMs may not be identified.
-
- Machine Type: This uses a byte in the BIOS ROM, and, on some machines,
- some extra information to determine the computer type, and
- in some cases, the exact model. If your computer is an AT
- or a 386/486, you get some extra information telling you
- about other hardware aspects of the computer. If you have
- a PC/XT type computer, and you see information about DMA
- channel 3 being used or not, you can probably disregard the
- information, as some clones don't properly support the
- function call used.
-
- BIOS source: INFOPLUS scans the computers main ROM BIOS, looking for a
- copyright message, which it displays.
-
- BIOS version: If you have a Phoenix BIOS in an AT or better, you'll
- find out the version.
-
- BIOS date: INFOPLUS displays what should be the date at a specific
- location in the ROM BIOS.
-
- BIOS extensions:Some add-in cards have ROM BIOS's of their own to handle
- special functions, and to extend the features of the
- computer. The most common are for the video and hard disk
- controller boards.
-
- Video BIOS's are found in all video cards except those that
- only support CGA or Monochrome graphics. It typcially
- starts at C000. (NOTE: I've noticed that some VGA cards lie
- about their size. If your VGA card supports extended modes
- such as 800x600, but the size shown is only 24K, then you
- might have problems with programs like QEMM and Windows 3.
- The BIOS's on these cards are really 32K. For QEMM, add the
- line X=C000-C7FF or ROM=C000-C7FF.)
-
- Unless you have an AT with an MFM or IDE controller, you'll
- probably have a hard disk BIOS at C800. Other common
- addresses are D800, and DC00. Some hard disk controllers
- have what seems like two BIOSs. One part is only needed at
- boot-up and for formatting the disk. The other is used to
- hold the 'real' parameters of the disk, and translate
- cylinder, head and sector counts into something else.
