This is similar to SPTD.sys (from Daemon Tools) kills my boot (Win XP Media Center Edition)
Over the last few weeks, I've been subject to frequent power-outages.
When my computer P4-1.7 2GB running Windows XP Pro experiences a power-outage whilst connected to the internet, I can not boot normally, using last known good configuration, or even into safe-mode. All attempts fail with a message to the effect that SPTD.SYS cannot be loaded. There are no SCSI components installed that I'm aware of ...
Boot succeeds only after the modem is also powered up, and link is active.
Why can SPTD.SYS not be loaded without the modem powered-up, and link active?
