**Later chipsets (basic spec):
**440 series:
***440FX (Natoma) 05/06/96...
***440LX (Balboa) 08/27/97...
***440BX (Seattle) c:Apr'98
Chips:
[82443BX] (PAC) [82371EB] (PIIX4E)
CPUs: Single or Dual P-II/P-III/Celeron
DRAM Types: EDO SDRAM Reg SDRAM ESDRAM
Mem Rows: 6 EDO, 8 SDRAM, 8 Reg SDRAM, 8 ESDRAM
DRAM Density: 16Mbit 64Mbit 128Mbit*1
Max Mem: 1GB
ECC/Parity: Both
AGP speed: 1x 2x
Bus Speed: 66 100 133*2
PCI Clock/Bus: 1/2 1/3 1/4*2 PCI 2.1
>*1 Only in C-1 and later steppings.
>*2 Exists but unofficially. There is no 1/2 divider for AGP,
making AGP unstable in a 133MHz bus system. In this config. the
system is overclocked.
