2.2 Detection of CPU/RAM/BUS
- Processor (type, CPUID)
- Memory (RAM)
- Bus (EISA, MCA, ISA, PCI)
2.3 Detection of CMOS
CMOS (Complementary Metal Oxide Semiconductor)
-
Test of CMOS presence (real-time bit)
Show 'CMOS size'
Show 'POST diagnostics status'
Show 'Shutdown/Reset status'
2.4 Detection of ROM‘s
ROM (Read Only Memory)
First scan memory from C000h:0000h to F000h:0000h with offset 200h (512 bytes).
After scanning it shows PnP/PCI informations about found ROM‘s.
2.5 Detection of FDD
FDD (Floppy Disk Drive)
- Detect device type of ATA FDD on on-board ATA controllers
- Detect count of FDD according to CMOS memory and BIOS detection
- If FDD is not present in CMOS settings, but is connected, it is neither possible detect
nor test FDD!
- Does it test of two FDD drives
- Test of presence FDD
- Test FDD with max. BIOS parameters – we got a type of drive
2.6 Detection of ATA/ATAPI on-board
It is perform detection of devices on primary (1F0h) and secondary (170h) channel,
tertiary (1E8h) and quaternary (1F0h) channel. On every channel are detected always
two devices: drive 0 and 1 (master and slave).
