From c05ab98fed9ea88714b04417b5331bff6ac974f1 Mon Sep 17 00:00:00 2001 From: eskere Date: Tue, 8 Jan 2019 13:45:35 +0100 Subject: Update KFSN4-DRE board info I have pointed out the various version of this board ("standard", 2S, iKVM, iKVM/IST, SAS, SAS/iKVM and SAS/iKVM/IST), and specified their differences and which CPUs they do support, also providing a link to the official ASUS website and to the board manual. Also I've tested the board with the text mode ROM and it's not usable (because it's jittery), so I'm suggesting to flash with the vesafb ROM. --- docs/hardware/kfsn4-dre.md | 51 +++++++++++++++++++++++++++++++++++++--------- 1 file changed, 41 insertions(+), 10 deletions(-) (limited to 'docs/hardware/kfsn4-dre.md') diff --git a/docs/hardware/kfsn4-dre.md b/docs/hardware/kfsn4-dre.md index e3974921..02b4dbcb 100644 --- a/docs/hardware/kfsn4-dre.md +++ b/docs/hardware/kfsn4-dre.md @@ -42,10 +42,35 @@ DDR2 533/667 Registered ECC. 16 slots.
