    • This invention concerns novel 3-[(3-alkylamino-2-hydroxypropoxy)phenyl]-1,2-propanediols of the formula: ##STR1## wherein R is selected from the group consisting of straight or branched-chain lower alkyls (C.sub.1 -C.sub.6) and cycloalkyls (C.sub.1 -C.sub.6); R.sub.1 and R.sub.2 are selected from the group consisting of hydrogen and 2,3-dihydroxypropyl, with the proviso that R.sub.1 and R.sub.2 may not be the same; and R.sub.3 is selected from the group consisting of lower alkyls (C.sub.1 -C.sub.4) and lower alkoxys (C.sub.1 -C.sub.4); and the acid addition salts thereof. These novel compounds are useful as antiarrhythmic agents and .beta.-andrenergic blockers in mammals.This invention also concerns novel compounds of the formula ##STR2## wherein R.sub.1 and R.sub.2 are selected from the group consisting of hydrogen and 2,3-dihydroxypropyl, with the proviso that R.sub.1 and R.sub.2 may not be the same; R.sub.3 is selected from the group consisting of lower alkyls (C.sub.1 -C.sub.4) and lower alkoxys (C.sub.1 -C.sub.4); and X is selected from the group consisting of ##STR3## and --CHOH--CH.sub.2 --Z (or a mixture of these compounds wherein X has both meanings stated above) where Z may be halogen, alkoxy sulfonyl and aryloxysulfonyl; and the acid-addition salts thereof. These compounds are useful as intermediates for the preparation of the active antiarrhythmic and .beta.-andrenergic blocking compounds described above.This invention also concerns a process for preparing said antiarrhythmic and .beta.-andrenergic blocking compounds from said intermediates.

    • An input/output device on a bus may be controlled to enable advanced features such as RAID to be implemented on a system board which is not otherwise specially adapted in any fashion to implement such features. The system board need not include, in its basic configuration, a host bus adapter such as one using an I/O processor, or standard BIOS instructions which assist in the implementation of the advanced features. The advanced features may be implemented by plugging an appropriate host bus adapter into an appropriate bus slot to provide the advanced functionality. By using special logic and signals on the host bus adapter, the advanced functionality may be achieved in a platform independent system board implementation and without the added cost of an I/O device on the host bus adapter.
    • 可以控制总线上的输入/输出设备,以使诸如RAID之类的高级特征能够在没有以任何方式特别适应于实施这些特征的系统板上实现。 在其基本配置中,系统板不需要包括诸如使用I / O处理器的主机总线适配器或有助于实现高级特征的标准BIOS指令。 高级功能可以通过将适当的主机总线适配器插入适当的总线插槽来实现,以提供高级功能。 通过在主机总线适配器上使用特殊的逻辑和信号,可以在独立于平台的系统板实现中实现高级功能,并且不会在主机总线适配器上增加I / O设备的成本。
