Modem trouble
Seeking help getting a modem to work in potato + some unstable. The modem is
on a Linksys EtherFast 10/100 + 56K Modem PC Card, model no. PCMLM56.
When the laptop was running Slink (installed from official CD set) the modem
worked but the ethernet did not. Now the ethernet works but the modem does
not. More details below, all help welcome.
Nick
The laptop brand is "M-TECH".
The bios:
(these descriptions appear during boot sequence):
SystemSoft MobilePRO BIOS Version 1.01 (2482-00)-(R1.14)
SystemSoft Plug-n-Play BIOS Ver 1.17.01
(version according to "Version Info" in BIOS setup):
1.00.03, Date: 10/22/97
PnP OS support is disabled.
In Win98, the modem and ethernet both work.
Here is what Win98 reports about the modem:
Port COM3
Interrupt 11
Address 3E8
UART NS 16550AN
On rebooting into Linux without switching power off, Linux does not see the
PCMCIA sockets.
Here is a portion of dmesg after rebooting from Win98 without switching off
power:
>>>
Linux PCMCIA Card Services 3.1.14

PCI routing table version 1.0 at 0xfe840
Intel PCIC probe:

not found.

<<<
Switching power off before booting makes the sockets visible to Linux. (I'm
not particularly worried about this, just reporting it in case relevant.)
Here is dmesg in full after rebooting from power off:
