Compatible with MMC system specification 2.0, SD memory card specification 1.0, and SDHC memory cards. Compatible with DOS, Linux, Windows 98SE, Me, 2000, XP, and Vista. Supports PIO, Multi-Word DMA, and Ultra DMA data transfer modes. SD-to-IDE Converter Interface Card Instructions: The power supply can be powered by a hard drive. This card only needs 5V power, and the normal operating voltage is 5V ±0.25V. The operating current is less than 200mA. Use an 80-pin hard drive cable for the IDE connector. Supports PIO, Multi-word DMA, and Ultra DMA host data transfer modes; the SD connector supports up to 128GB SD cards. After connecting the power supply and IDE cable, and inserting the SD card into the SD slot, the converter card acts like an electronic hard drive, and no driver needs to be installed. After installing the operating system, the OS (like Windows 98, etc.) can be booted from the SD memory card. Data transfer speed is high, roughly the same as the system's hard drive (ATA/133, U-DMA mode 3). Color: Black Material: PCB Size: 80 x 68MM Package Contents: 1 x Adapter Card
