Chipset
Intel 82430VX chipset, consisting of
82437VX System Controller
82371SB PCI I/O IDE Xcelerator
CPU
Socket: Socket 7
Supported CPUs:
Intel Pentium Classic, P54C, 75 - 200 MHz
Intel Pentium with MMX, P55C
Cyrix/IBM 6x86 P120+ - P200+ (P200+ support according to the manual)
Cyrix/IBM 6x86L, the new split voltage 6x86 CPUs
Cyrix/IBM M2, supports multiplier setting of 3.5 for M2
AMD K5 PR90 - PR166, according to the manual
Automatic detection of CPU type, setup with CPU SoftMenuTM in BIOS setup.
Supported CPU Voltages:
3.60 V
STD 3.38 V
VRE 3.52 V
2.50 V
2.70 V
2.80 V
2.93 V
Automatic detection of single or split voltage, setup with CPU SoftMenuTM in BIOS setup.
Supported Multiplier Settings:
x1.5, x2, x2.5, x3 for Intel Pentium CPUs
x2, x3 for Cyrix/IBM 6x86 CPUs
x2, x2.5, x3, x3.5 for Cyrix/IBM M2 CPUs
Setup with CPU SoftMenuTM in BIOS setup.
Supported Bus Speeds:
50 MHz
55 MHz
60 MHz
66 MHz
68 MHz ('turbo frequency' of 66 MHz)
75 MHz
Setup with CPU SoftMenuTM in BIOS setup.
Second Level Cache
 
Pipelined Burst Static RAM Cache
0 kB onboard, 0 kB in COAST slot
256 kB onboard, 0 kB in COAST slot
512 kB onboard, NO COAST slot
0 kB onboard, 256 kB in COAST slot
0 kB onboard, 512 kB in COAST slot
Maximum of 64 MB cacheable RAM, as usual for VX boards.

4 72 pin SIMM slots
no ECC support (VX chipset)
RAM types supported:
FPM RAM without parity
EDO RAM without parity
RAM sizes supported:
4 MB SIMM
8 MB SIMM
16 MB SIMM
32 MB SIMM
64 MB SIMM
2 168 pin DIMM slots
3.3 V unbuffered RAM
supports FPM and EDO and SDRAM
RAM sizes supported:
8 MB DIMM
16 MB DIMM
32 MB DIMM
Please note, that DIMM doesn't say SDRAM!!
Maximum RAM supported 128 MB, only to be accomplished via the SIMM slots. Please note, that you can't use any of the SIMM slots in case you are using both DIMM slots, due to the only 4 external (5 altogehter) CAS lines of the VX chipset. Each DIMM slot uses 2 CAS lines, each SIMM slot uses one CAS line.
Maximum of 64 MB cacheable RAM due to VX chipset.

PCI Bus

4 PCI slots, 3 full length
running at busclck/2
PCI specification 2.1
ISA Bus

4 ISA Slots, 2 full length, 2 2/3 length, one of the 2/3 length shared with PCI slot 4

Quote
33 cm x 22 cm full size AT. This means it's longer than the majority of the AT boards, which has the advantage that the CPU is quite far from the expansion slots. This enables you to use 2/3 length cards in each slot which isn't full length.
Super I/O

1 Floppy Port (up to 2.88 MB, Japan 3 Mode Floppy Supported)
2 Serial Ports (16550 Fast UART Compatible)
1 Parallel Port (ECP, EPP Port)
IrDA TX/RX Header (= infra red port support)
PS/2 Mouse connector
IDE Controller

2 x PCI Bus Master IDE ports (up to 4 IDE devices)
Support:
 
05:32
PIO Mode 3 & 4
DMA Mode 2
BIOS

Award Plug&Play BIOS, tested with revision '1S', flashable
Supports CPU SoftMenuTM which makes the board almost jumperless. All CPU settings are adjusted in the BIOS setup! Only one jumper for L2 cache size on board.
Supports bootable CDROM and bootable SCSI HDD, additionally you can boot from the first partition of any EIDE HDD connected, which means you can boot up to 4 different OSs via the BIOS setup.
Coming With

2 serial port ribbon cables, attached to a mounting bracket
1 parallel ribbon cable and PS/2 mouse cable, attached to a mounting bracket
1 IDE ribbon cable
1 floppy ribbon cable
floppy disk with
Bus Master IDE Driver for Windows95, OS/2, WindowsNT
BIOS Flash program
SoftMenu as program
Manual

Best manual I've ever seen, very coprehensive, BUT it's missing one thing! It doesn't tell you how you can mix SIMMs and DIMMs.
