# ASUS-Board

detailed information from heinrich@zsv.gmd.de:

- 3 PCI, 4 ISA Slots (3x16, 1x8 Bit)
- ZIF Sockel for the CPU
- room for 4 72pin-Simms (max. 128M)
- Award BIOS in Flash-Eprom
- Onboard: NCR-SCSI, 1par, 2ser (with FIFO), AT-Bus, Floppy

The board does like most in that price-class only write-through cache, no write-back. (which should not be grave, maybe 3% of performance?).

The BIOS supports scsi-drives under DOS/Windows without additional drivers, but with the board come addtitional drivers which are said to give better performance, for DOS/Windows(ASPI), OS2, Windows-NT, SCO-Unix, Netware (3.11 and 4, if interpreted correctly)

Gert Doering (gert@greenie.muc.de) was saying the SCO-Unix-driver for the onboard-SCSI-Chip was not working properly. After two or three times doing: "time dd if=/dev/rhd20 of=/dev/null bs=100k count=500" it kernel-panicked...

The trouble some people experienced with it might be due to them using an Adaptec-SCSI-Controller with "sync negotiation" turned on. Please check that in the BIOS-Setup of the Adaptec-1542C if you use one and have problems with occasional hangups!
