2. Upgradeability
Intel PCI to ISA /IDE Xcelerator BGA-324pin SL2MY
This section describes the major specification of user upgradeable part. CPU, Memory, and Extension slot
will provide the user to leverage the overall performance by adding or changing these part with other higher.
❑
CPU : CELERON processor-266MHz,300MHz
❑
Memory : EDO, SDRAM (2 Banks, 16MB - 256MB)
❑
Expansion slot : 2 master PCI, 2 ISA, and 1 shared slot
2-1 Processor
This motherboard supports a single Celeron processor. The processor’s VID pin automatically program the
voltage regulator on the motherboard to the required processor voltage. The motherboard supports
processors that run internally at 266/300MHz.
❑
Packing
