PCMCIA/Memory Hardware Problem
Hi,

I have a Dell Inspiron 4000 that I am using to run Redhat Linux 7.1.
This machine had 128Mb of RAM in it, and I upgraded to 512Mb.

Since this, the PCMCIA cards have disappeared from the system running under Linux, although they still work under windows and the file "/var/lib/pcmcia/stab" only contains:
Code:
Socket 0: Empty
Socket 1: Empty

but another machine we have with the same cards shows:
Code:
Socket 0: 3Com 3CCFE575CT/3CXFE575CT Fast EtherLink XL
0       network 3c59x   0       3c59x
Socket 1: Serial or Modem
1       serial  serial_cs       0       ttyS1   4       65

If we take the memory out and use anything less than 512Mb the cards will work again, but not when 512Mb is installed, despite the fact that the BIOS and motherboard of this computer is supposed to handle this amount.

Is there any special method to allow this to work with 512Mb, without having to reinstall?

hciattach

HCIATTACH(8)						    Linux System Administration 					      HCIATTACH(8)

NAME

       hciattach - attach serial devices via UART HCI to BlueZ stack

SYNOPSIS

       hciattach < tty > < type | id > [ speed ] [ flow ]

DESCRIPTION

       Hciattach is used to attach a serial UART to the Bluetooth stack as HCI transport interface.

OPTIONS

       <tty>  This specifies the serial device to attach. A leading /dev can be omitted. Examples: /dev/ttyS1 ttyS2

       <type | id>
	      The  type or id of the Bluetooth device that is to be attached, i.e. vendor or other device specific identifier. Currently supported
	      types are

	      type   description

	      any    Unspecified HCI_UART interface, no vendor specific options

	      ericsson
		     Ericsson based modules

	      digi   Digianswer based cards

	      xircom Xircom PCMCIA cards: Credit Card Adapter and Real Port Adapter

	      csr    CSR Casira serial adapter or BrainBoxes serial dongle (BL642)

	      bboxes BrainBoxes PCMCIA card (BL620)

	      swave  Silicon Wave kits

	      bcsp   Serial adapters using CSR chips with BCSP serial protocol

       Supported IDs are (manufacturer id, product id)

	      0x0105, 0x080a
		     Xircom PCMCIA cards: Credit Card Adapter and Real Port Adapter

	      0x0160, 0x0002
		     BrainBoxes PCMCIA card (BL620)

       <speed>
	      The speed specifies the UART speed to use. Baudrates higher than 115.200bps require vendor specific  initializations  that  are  not
	      implemented for all types of devices. In general the following speeds are supported:

	      9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600

	      Supported vendor devices are automatically initialised to their respective best settings.

       <flow> If  the  keyword	flow  is  appended to the list of options then hardware flow control is forced on the serial link ( CRTSCTS ). All
	      above mentioned device types have flow set by default. To force no flow control use noflow instead.
