Allow Windows 95 to supply all 32-bit drivers for your PCMCIA port. Do not use Cardsoft or CardWiz DOS drivers. If they are found in the Config.Sys file, backup the file and remove the appropriate lines.
From the Windows 95 list of supplied drivers, choose the SCM Swapboy (non-Plug 'n Play) driver for the DYO drive.
SYMPTOM: Can't locate or assign a drive letter. Doesn't show up with a drive letter assigned under My Computer.
REASON: Actually, it works with all PC Cards except ATA storage devices such as ATA Flash or ATA HDDs. The Dyo is not a plug and play device therefore it expects to use certain interrupts and I/O addresses. The interrupt and I/O address it requires are the same as a secondary IDE port. INT 15, I/O 170-177. When a device such as a second IDE drive or CD ROM player is attached to the 2nd IDE controller it takes INT 15 and I/O 170-177, which conflicts with the Dyo's requirement to use these same resources.
FIX: There are 2 ways this can be fixed:
Note: The resources for the Dyo can not be modified.
1. In most cases you can change the INT and I/O range on the 2nd IDE port through the BIOS, especially if this is a PCI device. Or, you may even be able to change these resources through the Windows 95 System menu.
2. Or, an alternative fix is to remove the device from the secondary IDE controller. In the case of a CD ROM, re-connect it to the sound board instead of the IDE controller, or for a drive, attach it as a slave drive to the 1st IDE controller.
CONFIGURATION: Windows 95 will automatically set the Dyo drive up as a PCIC compatible PCMCIA controller. This is will work fine. Later versions of Windows 95 include a driver specific to the Dyo drive, which can be manually entered through "Add new hardware", PCMCIA socket, SCM Swapbox, SCM Swapbox Family Controller. Do NOT choose the PnP driver. However, it really isn't necessary to choose this driver because the PCIC compatible PCMCIA controller works fine.
PCMCIA utilty programs and drivers for Windows 3.1 / 95 / NT can be obtained from System Soft at local software dealers or directly from the company.
PCMCIA Disk Drive Not Seen In Windows 95
A resource conflict may exist if the PCMCIA disk controller is configuredto use I/O ports 170-177 and your computer uses the same ports for someother purpose.
Examine the computer settings in Device Manager. If the PCMCIA disk controller is using ports 170-177, try either of the following methods to resolve the conflict:
- Reserve I/O ports 170-177, forcing Windows 95 to configure the PCMCIA disk controller at another I/O address. To do so, follow these steps:
1. In Control Panel, double-click the System icon.
2. On the Device Manager tab, click Properties.
3. On the Reserve Resources tab, click the Input/Output (I/O) option button, and then click Add.
4. In the Start Value box, enter 170.
5. In the End Value box, enter 177.
6. Click OK until you return to Control Panel
7. Restart your computer.
Windows 95 will not configure any device to use I/O ports 170-177 if it can avoid doing so.
- Try disabling any secondary disk controller that uses I/O ports 170-177 in the computer's CMOS settings.
