SDHC Card Support
« on: August 01, 2025, 06:25:12 pm »
Using a Thinkpad T530 - it has an SD Card slot, collecting dust.

Should I be able to pop-in an SDHC
card and use minilvm to format it?

Would the recommendation be FAT32 or JFS?

Is the backend for this the usbmsd?

Hello Dan

As far as a I know there are some SD Card slots that are based in a different interface which we don't have driver on OS/2. I don't remember if it was I2C or other name. . If it is "eMMC", we don't have driver for it. (please someone correct me)

Does you MMC/SD Card Slot is working on ArcaOS? Do you see it on any report? lsusb, pci.exe ? Does it show as a drive on lvm?

Here it is the Specs of the T530 on the Lenovo PSREF, but I can not be sure if it is eMMC yet.

Dan, can I add the you Thinkpad T530 information to the OS2World wiki? Can you share with me the TESTLOG report  and lsusb report? Please let me know what works and what don't.

Regards

Thanks Dan

Your machine has Firewire (IEEE 1394). We have a driver for it, but no implementation for any Firewire device, so it is useless ;D

Here it is my first take on your hardware.

Let me know any corrections or remarks you want to add. Did you disable something on the BIOS to make it install? Any tricks there?

Hello Dan

The SD Card reader is the "Ricoh PCIe SDXC/MMC Host Controller - 1180:E823". I don't have any report of anything similar working on OS/2. Seems to bee PCIe.

The wiki looks awesome.

As for the install.
  I changed the bios to secure boot off,
     no uefi,
      legacy,
        csm on.

I had one quirk in the install, I logged it on Mantis [which I can't access at the moment]

 I think it's the 3rd reboot, startup.cmd installs things, like the bar on the bottom of the screen.
  Mine abended on product 29 or 27.

 I worked around that, by moving startup.cmd to dan_startup.cmd, rebooting.
   starting cmd.exe and running dan_startup.cmd by hand - and it completed.

Last week, I read all the help / wiki files on arcanoea.com,
  This week I read through everything in /sys/doc.

I expect that it is the same as the slot in my ThinkPad L530. I never got it to work. The simple solution was to get a USB SD card adapter. I got a Kingston device (Realtek internally). It started to work with the Arca Noae USB stack, a few releases ago.

There may be a better option, unless you use the SD card with another device. I have a couple of USB external drives, using SABRENT enclosures, with Crucial NVME sticks. They work far better than SD cards (and adapters).
