Maintenance and Service Manual:
NO mention of Cardbus, 32 bit, or 32bit
There are 16 bit Type II and Type III slots and cards, and Type II and Type III Cardbus slots and cards. All Cardbus slots are 32 bit, but are backward compatible with 16 bit cards.
If the laptop supports Cardbus, that's almost always mentioned in the specs for the laptop, and in the manuals for the laptop, often many times.
The Maintenance and Service Manual for this series does not mention Cardbus, or 32 bit, or 32bit, so it probably cannot support Cardbus cards.
Cardbus cards cannot physically plug into 16 bit card slots because of the way the edges of the card and 16 bit slot are designed, so if a Cardbus card won't plug it, the card slot is definitely 16 bit, only.
"# I have a old notebook computer with only a 16-bit slot. Is there a way I can get a 16-bit PC Card to support Firewire or USB 2.0?
While it may be technically possible to get these interfaces working on a 16-bit slot, it probably wouldn't work too well. The 16-bit interface has a maximum theoretical data rate of approximately 20MBytes/second. The actual maximum is probably closer to 1/4 or 1/2 of that (40 to 80Mbits/sec). USB 2.0 is spec'ed at 480Mbits/sec and Firewire is 400Mbits/sec. The data rates of these modern interfaces are too high for the 16-bit PC Card interface and 386/486/P1 class machines. We know of no 16-bit PC Cards that support these modern interfaces. "
There may have been USB 1.0 or USB 1.1 PC Cards at one time (there were USB 1.x PCI cards for desktop computers - I have one), and if so , that would probably work in a 16 bit slot, but when I searched it seems there are no new USB 1.0 or 1.1 PC cards, and I couldn't find any used ones either.
Also, there's the problem of USB 2.0 controller drivers. Usually the PC card does not come with 98SE drivers and they are not available on the manufacturer's website.
Windows 98SE and previous Microsoft operating systems have NO built in support for recognizing flash drives, or USB 2.0 controllers; Windows ME was the first Microsoft operating system that supported recognizing flash drives.
It used to be flash drives and USB cards came with Windows 98, and/or, more often, 98SE drivers that you could install, but that's no longer the case. You can still download 98SE drivers from a few flash drive manufacturer's web sites, but I've found these drivers to be a better solution.....
If you're not sure whether you have Windows 98 or 98SE, RIGHT click on My Computer - Properties.
Whether it is 98 or 98 Second Edition is shown on the right on the first page you see.
Generic USB Mass Storage drivers.
These allow many USB devices that have no drivers for 98 and 98SE to work in those operating systems.
Win98 original, modified from the 98SE version.
"Remove ALL drivers for USB flash drives in Device Manager"
NOTE that I have not had to Un-install previously installed drivers.
If you want to do that, those are listed in Control Panel - Add/Remove Programs.
The 2.x versions support the recognition of many USB devices.
The 3.x versions also support the recognition of USB 2.0 controllers.
NOTE that the 2.x versions have NO Un-install; the 3.x versions DO - in Add/Remove Programs.
After you have installed these drivers, after you have plugged in or installed a USB device that hasn't been plugged in or installed before, you are prompted to have Windows search for drivers - do that, it will find the drivers, and that same USB device is detected automatically when it's plugged in or installed after that.
These drivers work for many devices, but there are some they can't detect.
E.g. Apple never made drivers for their devices for previous to Windows 2000, so an iPod , iPod Shuffle, iPod Nano, etc., cannot be recognized.
