The UP1000 is a motherboard built by Samsung and API NetWorks and released in 2000.
Hardware
- 600 MHz with 2MB L2 or 700 MHz with 4MB L2 EV67, L2 cache bandwidth 3.2GB/s [1]
- AMD-751 Chipset, ALi M1543C south bridge
- 3x 168-pin DIMMs, supports 64MB to 768 of ECC unbuffered PC100 SDRAM
- 1x AGP 2x (See limitations below)
- 4x 33 MHz 32-bit PCI slots
- 2x EISA slots
Limitations
- The IDE controller does not support 48-bit LBA, so hard drive sizes are limited to 128 GiB (137GB)
- According to Ivan Kokshaysky, the UP1000, UP1100, and UP1500's AGP is limited to PCI transfers:
| “
| There is quite fundamental conflict between the Alpha architecture and x86 AGP implementation - Alpha is entirely cache coherent by design, while x86 AGP is not (I mean native AGP DMA transactions, not a PCI over AGP). There are no such things as non-cacheable mappings or software support for cache flushing/invalidation on Alpha, so x86 AGP code won't work on Nautilus.
