- not an AMI BIOS?
-
- We've several 486DX machines in the lab at work with AMI BIOSs. The features
- provided by this BIOS (e.g. configurable NUM LOCK at start-up, drive boot
- order chosen by user, and many others) was one of the reasons when I bought
- my own 486DX that I specified an AMI BIOS.
-
- Now, my machine has an AMI BIOS in it, *but* it only implements a small
- sub-set of the features of the machines in the lab. The two features
- I give as examples as above are missing, as is a number of others.
-
- I'm slightly puzzled! I can understand that certain BIOS features (ROM
- shadowing, memory wait states, etc) are functions of the chipset and
- perhaps the motherboard: however I would have thought that the startup
- NUM LOCK state (for example) could be user-configurable on any machine.
-
- I'm further confused in that looking through a "Buyers' Guide" for 486 PCs,
- there are PCs listed with identical motherboards, identical chipsets, with
- AMI BIOSs, *but* with different BIOS features.
-
- So I'm wondering whether I've been sold a pup? Looking through the BIOS ROM
- area of memory, I can see all the text strings for the options that don't
- appear. Is there perhaps a table of flags in the ROM which controls which
- features are implemented in a particular ROM? Or do I need to buy a full-
- spec AMI BIOS to get the extra features?
