The following is a description of the TOPS FlashCard for the PC, which is available from Sun Microsystems, Inc. For more information on the TOPS FlashCard, call Sitka Technical Support at (415) 549-8737.
The following are the system requirements for the TOPS FlashCard:
- IBM-compatible computer
- MS-DOS version 2.00 or later
The TOPS FlashCard has six jumpers that can be used to change the board's I/O address, IRQ line, and DMA channel. The following diagram shows the relative position of the jumpers on the TOPS FlashCard (where X denotes the default jumper position):
____________________________________ | | | Ja1 | | X H | | : L | | | | Ja2 Ja3 Jint Jd2 Jd1 | | X : : X : X X : X : | | L H L H 3 2 1 3 1 3 | |____________________________________| Jumper Description Default ------------------ ------- Jint Interrupt 2 Jd1 DMA Acknowledge 1 Jd2 DMA Request 1 Ja1 I/O Address(398) High Ja2 I/O Address Low Ja3 I/O Address High
The AppleTalk driver used by the TOPS FlashCard to communicate with the AppleTalk network depends on the version of TOPS/DOS software being used. TOPS/DOS version 2.0 uses the ATALK.SYS driver, which must by installed from the CONFIG.SYS file of the boot disk. TOPS/DOS versions 2.1 and 3.0 uses the ALAP.EXE driver, which can be installed from the AUTOEXEC.BAT file of the boot disk or the DOS prompt. For more information on these drivers, query on the following words in the Microsoft Knowledge Base:
TOPS and drivers and Mail
Both drivers can use the following switch settings for custom installations that are different from the default settings of the FlashCard. If there are no changes from the default jumper settings, no switches should be used. The /FLASHTALK option allows two FlashCards to communicate at high speeds, and is not required for running the Microsoft Mail MS-DOS client. The following is a list of available options:
Option Default Other Possible Values ------------------------------------------------------------------ /BOARDINT=x 2 3 /DMA=x 1 3 (AT only), none /ADDRESS=xxx 398 390,310 /INT=xx 5C Any unused interrupt (5C-6F) /FLASHTALK=x Enabled(1) Disabled(0)
The default factory settings for the TOPS FlashCard for the PC use interrupt 2, which conflicts with the hard disk controller of an IBM PC/AT or compatible computer. When you run the Mail MS-DOS client with the TOPS FlashCard, it is recommended that you set the board interrupt to 3 and the software interrupt to 60. With these suggested settings, the command to load the AppleTalk driver for the TOPS FlashCard should include the /boardint=3 and /int=60 switches.
