little more reliably. So far I've received a couple of positive responses and no objections to these changes. There are two one-line changes: - In wdprobe(), when testing the error status of drives, don't unconditionally decide that there is no controller present if we read back a value of 0x81 (drive 0 okay, drive 1 failed) twice in a row. This may be caused by having an ATAPI CD-ROM jumpered as a master on the controller with no slave. - In wdgetctlr(), when checking for a status of WDCS_READY, check the value twice. The first time may be bogus. This stops a phantom wd2 device from being detected when an ATAPI CD-ROM is attached to the secondary controller alone as a slave. (This can cause installation to fail when sysinstall attempts to open the phantom device and wedges the system as a result. This has bitten me a couple of times on some Gateway 2000 machines.)
