1.1 Introduction
Figure 1-1: IOWA-GX
The IOWA-GX is an AMD Geode™ GX based based half-size ISA CPU card. The
IOWA-GX has a Front Side Bus (FSB) of 333MHz, 128MB of RAM on-board and is
upgradeable with a further 512MB of SDRAM. Multiple input/output options include VGA
and 24-bit TTL for video output, a parallel port, two serial ports, an infrared port and
10/100BASE-T Ethernet. The IOWA-GX supports up to two IDE drives and one floppy
drive. Two SATA ports with RAID 0 and RAID 1 capabilities are optional.
1.1.1 IOWA-GX Models
The IOWA-GX series has two models:
IOWA-GX-466-128MB-R11
IOWA-GX-466S-128MB-R11
The specifications for the four models are show in Table 1-1.
