Enable the built-in SD card reader of the notebook to read the sdhc

My laptop is Dell's d430 and comes with an SD card reader, but the newly purchased sdhc 4G card cannot be read.

I know that the electrical definition of sdhc is no different from that of SD, so I should update the software to be compatible with sdhc. Of course, this is just a matter of principle. However, I did find a Microsoft XP patch on the internet, saying that Windows XP can recognize a larger SD storage medium. However, this is only the core of the XP operating system layer. We have to say whether the SD card reader chip is supported.

After downloading and installing the patch, I was surprised that d430 directly read the sdhc content at a time. It seems that the firmware of the original SD adapter chip supports sdhc, And I am lucky enough. Otherwise, I have to go online to find its chip information and download the latest firmware.

Haha, you can also test whether your laptop has a built-in SD card reader, and whether it is as simple as my laptop. 4G sdhc is really refreshing. Haha.

If you go home at night and try the 700 m of Dell, the old laptop, at home again, I hope it will be so simple.
