PCMCIA Card Booting on IBM Thinkpad 360c

#1 Post by Firecharger » Fri Jul 11, 2025 6:08 pm

I currently have an ibm thinkpad 360c with a pcmcia Sony memory stick adapter, and have pc dos installed on a 16mb memory stick. Now the computer seems to be able to recognize this card as storage and access it without any drivers, but I’ve never been able to get the computer to boot from this memory stick, even by setting the pcmcia card slot first in the startup order in easy setup. I currently am using a floppy disk with command.com to startup, but I was wondering if it is possible to get the computer to boot from my memory stick in the pcmcia card slot?

I never tried to boot form a memory stick. But with CF cards it's important to partition the card with the right tool to make it bootable.
You may want to read this posts and try to partition your memory stick accordingly and see if it works viewtopic.php?f=6&t=132765&p=860108&hil ... ix#p860104
so the steps are:
- partition with pcmfdisk.exe
- format with format.exe with /S switch

Check this thread: viewtopic.php?f=6&t=132765&p=884581#p884581 and this table: https://www.thinkwiki.org/wiki/Supporte ... red_Series as I've just tested it and as long as you have the correct industrial CF card, it will boot from PCMCIA CF.

The OP has a Sony memory stick, not a CF card. Have you tried to boot form anything other than a CF card?
I vaguely remember using a CF to microSD adapter. It kind of worked in DOS, but with some glitches. Didn't try to boot from it, though.

I know, but I just wouldn't bother. What would be the point or the gain? It's just complicating matters by using anything other than CF with PCMCIA.

Just another update and will update the wiki. The 535E will boot from PCMCIA and the Easy Setup is clever enough to not allow you to enable both the HDD0 and PCMCIA at the same time (presumably as they conflict).

It will boot happily from up to a 4Gb CF card but on whatever card you use Win98 fails at 11 minutes to go. Tried this several times - it just can't cope. So you can boot from PCMCIA and run DOS and Windows, but you can't install Win98!.
