Compatible with MMC system specification 2.0, SD memory card specification 1.0, SDHC memory card. Compatible with DOS, Linux, Windows 98SE, Me, 2000, XP, and Vista. Supports PIO, Multi-Word DMA, and Ultra DMA data transfer modes. Instructions for SD-IDE conversion interface card: The power socket can be powered by a hard disk. This card only needs to be powered by 5V, and the normal working voltage is 5V±0.25V. The working current is less than 200mA. For the IDE socket, use an 80-pin hard disk cable. Supports PIO, Multi-word DMA, and Ultra DMA Host data transfer mode; the SD socket supports up to 128GB SD cards. After connecting the power supply and IDE cable, and inserting the SD card into the SD socket, the conversion card is equivalent to an electronic hard disk, and no driver needs to be installed. After installing the operating system, the operating system (e.g., Windows 98, etc.) can be booted via the SD memory card. The data transfer rate is high, and the speed is approximately the same as the system hard disk (ATA/133, U-DMA mode3).
